bro·mine. (brō′mēn) Symbol Br. A dense, volatile, corrosive, reddish-brown, nonmetallic liquid halogen element that exists as a diatomic molecule, Br2 having a highly irritating vapor. Chiefly isolated from brines, it is used in producing fumigants, dyes, water purification compounds, and photographic chemicals.
Also asked, what is br2 in chemistry?
Bromine | Br2 – PubChem.
Similarly, is br2 an element? There are only seven elements that can exist as molecules they are H2, O2, N2, F2, I2, Cl2, Br2. Compounds consists of atoms of two or more different elements bound together like two hydrogens chemically bond to one oxygen.
Similarly one may ask, what is the difference between BR and br2?
Difference between Br2(aq) and 2Br-(aq) Aqueous bromine simply means Br2 that has been dissolved in water. Br- is the form of bromine in which an electron has been gained (full outer shell).
What is bromine solution?
BROMINE SOLUTION is an oxidizing agent. Bromine disproportionates rapidly in basic water to give bromide ion and bromate ion. The latter is also an oxidizing agent. Dissolution lowers reactivity compared to pure bromine.

What is br2 called?
Br2 is called as diatomic bromine. It is a fuming reddish brown liquid at room temperature and evaporates readily to form a similarly coloured gas.
What is h2 called?
H2 is also called molecular hydrogen.It consists of two protons and two electrons. Consequently it is the most common form of Hydrogen because it is stable with a neutral charge. H2 is not a free radical. It is the antioxidant in ‘hydrogen-rich’ water. H2 is the smallest molecule in the universe.
Is br2 a gas?
Chlorine, Cl2, is a gas at room temperature, but bromine, Br2, is a liquid.
Is br2 gas or liquid?
Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine.
Is BR diatomic?
Diatomic elements are pure elements that form molecules consisting of two atoms bonded together. There are seven diatomic elements: hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine, bromine.
What is the pH of bromine?
Bromine tablets generally have a pH around 4, therefore, pH adjustment to the water will be necessary to maintain proper water balance. Even though bromine is effective over a wide pH range, it is important that the ANSI/APSP/ICC-11 recommended pH range of 7.2 to 7.8 and alkalinity range of 60 to 180 ppm be maintained.
Is br2 acidic or basic?
Br2 and Br+ are soft Lewis acids and Br- has properties in between soft bases and hard bases. Hence Br2 is considered to be a soft Lewis acid.
What is bromination reaction?
Bromination: Any reaction or process in which bromine (and no other elements) are introduced into a molecule. Bromination of an alkene by electrophilic addition of Br2. Bromination of a benzene ring by electrophilic aromatic substitution. Bromination of a benzylic position by a free radical substitution reaction.
What type of bond is br2?
Answer and Explanation: Each bromine atom has seven valence electrons. The two atoms try to form a covalent bond by sharing electrons, that will result in both atoms having a
Is br2 aqueous?
So it is generally represented as Br2(aq). Bromine water is a highly oxidizing intense yellow to red mixture containing diatomic bromine (Br2) dissolved in water (H2O).
Why is bromine written as br2?
Why is the formula for bromine Br2 in liquid state and not Br? In gas phase bromine atoms have energy enough to be inde Liquid state bromine is a diatomic molecule because the system’s energy is lower in the one composed by a molecule that in the one composed by two bromine isolated atoms.
What is the chemical formula of bromine?

Is sugar a mixture?
A compound is what table sugar is. Sucrose is made of three elements: carbon, hydrogen, and oxygen. Each “element” can be identified and separated from the other through physical means. Sugar can be mixed into all kinds of things to create a mixture or a solution, but the sugar itself is a compound.
Is co2 a molecule?
Carbon dioxide is a molecule with the molecular formula CO2. Carbon dioxide, CO2, is a colorless gas. It is made of two oxygen atoms covalently bonded to one carbon atom.
