Is bromine a chemical or physical property?
This indeed is a chemical property. The element bromine is the same as a liquid or a gas. The change from liquid to gas is a physical change. The temperatures and pressure at which that change happens is a physical property.
What is the chemical symbol for bromine?
The chemical symbol for Bromine is Br. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. The nucleus is composed of protons and neutrons. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.
What state of matter is bromine in at 332 K?
(4) Bromine changes from a liquid to a gas at 332 K and 1 atm. Solid, liquid and gas are physical states of the matter. The element bromine is the same as a liquid or a gas.
What is the electronegativity of bromine?
Electronegativity of Bromine is 2.96. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion.
