Key Stage 2
Meaning
Key Stage 3
Meaning
Bromine is a Group 7 element, on the Periodic Table, with an atomic number of 35.
About Bromine
Molecular Structure
- Bromine has the chemical formula Br2.
Atomic Structure
- Bromine as 35 protons and 45 neutrons in its nucleus giving it an Atomic Number of 35 and an atomic mass of 80.
- An atom of Bromine is missing one electron from having a full outer shell.
- Bromine ions gain 1 electron to get a full outer shell and become negatively charged.
Properties
- Bromine is a more reactive Halogen than Iodine but less reactive than Chlorine.
- Bromine reacts strongly with Hydrogen to produce Hydrogen Bromide which dissolves in water to produce Hydrobromic Acid.
- Bromine is a bleaching agent.
- Bromine kills bacteria.
- Bromine is a pale green coloured gas at room temperature.
