It is a halogen, found in the periodic table in group 17. Bromine has been known since ancient times, and its discovery is credited to carl jacob löwig in 1825.

Bromine has many uses due to its unique properties. In its elemental form, bromine is a reddish-brown liquid that evaporates easily at room temperature. It has a strong smell, similar to that of chlorine or bleach, and it reacts with metals and other elements to form compounds called bromides. Bromide compounds are used as flame retardants in plastics and textiles, as well as disinfectants for swimming pools and hot tubs.

Bromine also finds use in photography as an intensifying agent for photographic emulsions; it helps make images brighter by increasing the amount of light absorbed by the film or paper used for printing photographs. The element also plays an important role in organic chemistry; it is used to produce brominated organic compounds such as pharmaceuticals, dyes and pesticides.

Bromine’s history stretches back thousands of years before its official discovery by carl jacob löwig in 1825. Ancient egyptians were known to use brines containing bromide salts for medicinal purposes such as treating skin diseases like psoriasis; these brines were likely produced from naturally occurring deposits of rock salt containing traces of bromide ions from nearby volcanic activity or ocean water seeping into underground caverns containing seawater.


In the medical field, bromine is used as a disinfectant and antiseptic in swimming pools and hot tubs to help prevent the spread of bacteria, viruses, and other contaminants. It’s also used in certain medications such as sedatives and anti-anxiety drugs.

Biological function

Bromine is essential for the proper functioning of the human body. It helps regulate hormones, maintain cell membrane stability and assists in metabolism. Bromide ions are necessary for normal nerve impulse transmission and are involved in the breakdown of certain amino acids. In addition, bromide can help reduce inflammation and boost immunity.

The benefits of bromine go beyond just its biological functions though; it is also used as a disinfectant and preservative in food products and medicines, as an additive to gasoline to reduce engine knocking, and as an ingredient in photographic film development. Brominated flame retardants are also used extensively in electronics manufacturing to protect against fire hazards.

Health effects from bromine

Bromine is found naturally in soil, plants, and sea water. It can also be produced synthetically for industrial use. Bromine has many uses including flame retardants, pharmaceuticals, dyes, photographic chemicals, agricultural pesticides and more.

When it comes to human health effects from bromine exposure, there are both positive and negative aspects to consider. On one hand, bromine plays an important role in metabolism by helping regulate hormones and other bodily functions. It also helps protect against cell damage caused by free radicals that can lead to diseases like cancer or heart disease over time.

On the other hand, excessive exposure to bromine can cause serious health problems such as skin irritation or respiratory issues like asthma or bronchitis. In extreme cases it may even lead to organ damage or death if ingested in large amounts over time. To avoid these potential risks it’s important to limit your exposure to brominated products as much as possible and wear protective gear when handling them directly at work or home.

What are the valences electrons of bromine

Bromine is non-metallic. The number of electrons within the shell after the last orbit is known as the valence. The valence of bromine is the sum of all electrons found in the shell following the electron configuration. The element’s properties are determined by the presence of valence electrons, which also play a role in bond formation.

Valence is the ability of an atom of a chemical element to form a certain number of chemical bonds with other atoms. It takes values from 1 to 8 and cannot be equal to 0. It is determined by the number of electrons of an atom spent to form chemical bonds with another atom. The valence is a real value. Numerical values of valence are indicated with roman numerals (I,II, III, IV, V, VI, VII, VIII).

How do I calculate the number valence electrons within a bromine atom

Following a few steps, you can determine the valence of electrons. One of these steps is the electron configuration. Without the electron configuration, it’s impossible to determine valence electrons. It is simple to identify the electron configuration of all elements.

However, valence elements can be identified by organizing electrons according to Bohr principles. This is how we can determine the valence of bromine.

Finding the total number electrons in bromine

We first need to determine the total number electrons in the bromine-atom. The number of protons present in bromine is required to calculate the number of electrons. You will also need to know the atomic numbers of the elements of bromine to determine the number of electrons.

The periodic table can be used to calculate the atomic numbers. The periodic table has the information necessary to determine the atomic number for bromine elements. The number of protons in an atom is the atomic number. Additionally, electrons equal to protons can be found outside of the nucleus.

We can thus conclude that electrons are equal to the atomic numbers in the bromine-atom. We can see that the atomic amount of bromine is 35 from the periodic tables. The total number of electrons in a bromine atom is therefore 35.

The terms “oxidation degree” and “valence” may not be the same, but they are numerically almost identical. The conditional charge of an atom’s atom is called the oxidation state. It can be either positive or negative. Valence refers to the ability of an atom form bonds. It cannot have a negative value.

Bromine needs to be electron-configured

Important step 2. The arrangement of the electrons of bromine is required in this step. The total number of electrons in bromine atoms is thirty-five. The electron structure for bromine shows that there is two electrons inside the K shell. There are eight electrons in each of the L shells. Eighteen electrons are in the M shell. Seven electrons are in the N shell.

This means that the bromine shells have two electrons each, eight electrons in the second, eight in the third, eighteen electrons in the third, and seven electrons in the fourth. There are two shells of bromine with eight electrons each: 2, 8, 18 and 7.

Besides, do BR have 8 valences electrons?

Bromine contains 7 valance electrons. The rightmost column of the periodic table has 8 valance electrona or a complete shell.

How can you determine how many electrons it takes to fill the outer shell?

Bromine can be used for many purposes, including agricultural chemicals, dyestuffs. insecticides. Pharmaceuticals and chemical intermediates. While some uses have been discontinued due to environmental concerns, new uses can still be found. Bromine compounds may be used as flame retardants.

  1.  The valence is a numerical characteristic of the ability of atoms of a given element to bond with other atoms.
  2. The valence of hydrogen is constant and equal to one.
  3. The valence of oxygen is also constant and equal to two.
  4. The valence of most of the other elements is not constant. It can be determined by the formulas of their binary compounds with hydrogen or oxygen.

Calculate total electrons by determining the valenceshell

The third step involves diagnosing the valenceshell. The valenceshell is the shell that follows the electron configuration. The total number of electrons contained in a Valence Shell is called valence. The electron configuration indicates that the last bromine shell has seven electrons. Bromine’s valence electrons (Br), are therefore seven.

How do you calculate the number of valence electrons in a bromine atom

What is the valency for bromine?

Valency is the ability for an element’s one atom to bond with another during the formation a molecule. The element’s valency refers to the number of electrons that remain unpaired in its last orbit. Bromine(Br), in its correct electron configuration, will be 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4px2 4py2 4pz1.

This electron configuration shows that the bromine atom’s last shell contains an unpaired electron. Bromine’s valency is therefore 1. The electron configuration of an element in its excited state determines its valency. Bromine atoms absorb energy when they are excited. A bromine atom in the 4py sub-orbital is excited and then jumps to its 4dxy1 orbital.

What is the valency of bromine

The electron configuration of bromine (Br*), in excited state, will therefore be 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4px2 4py1 4pz1 4dxy1. Bromine is composed of three unpaired electrons. Bromine’s valency in this instance is 3. Bromine atom can be found in -1, 1, +1, +3, or +5 oxidation states. The bond formation can affect the oxidation status of an element.

How many protons or electrons does bromine possess?

The nucleus is located at the center of an atom. In the nucleus are protons and neutrons. 35 is the atomic quantity of bromine. The number protons is what the atomic number refers to. This means that the number protons in bromine equals thirty-five. A circular shell is located outside of the nucleus and contains electrons equal to protons. A bromine atom can have up to thirty-five electrons.

How many orbitals does BR possess?

Let’s look at the bromine atom to understand this principle. Bromine (Z=35), with 35 electrons can be found in Period 4 Group VII of the periodic tables. Bromine is 7 valence electrons so the 4s orbital with 2 electrons will be filled. The remaining 5 electrons will then occupy the 4p orbital.

Why use noble gas notation?

noble gases is that uses to summarise the electron configuration for an element and provide the most pertinent information about the element’s valence electrons. To represent all electrons not valence electrons, the noble gases can be substituted.

How many valence elements does bromine (Br ) contain?

During bond formation, the elements with 5, 6, and 7 electrons in their last shells are able to receive electrons from the last shell. Anions are the elements that receive electrons to form bonds. Bromine’s last shell receives an electron when it forms a bond. This is called a bromide Ion (Br ). This is why bromine is called an anion element.

How many valence electrons does bromine ion(Br–) have

Bromide Ion’s electron configuration (Br) is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6. The electron configuration shows the bromide-ion (Br ) has obtained the configuration of krypton. The eight electrons in the last bromine ion shell indicate that the valence electrons are eight for the bromine electron ion (Br ).

How can you gain or lose electrons?

When atoms are deprived of electrons or gain electrons they become what is called an ion. An atom that loses electrons has a net negative charge. This is known as a cation. Loss of electrons causes an atom to have a net negative charge. The atom is known as an anion.

How many electrons does bromine have?

A bromine atom has 35 electrons. A bromide-ion (Br) has 36 electrons.
