What is chlorine at room temperature
A greenish gas
What is bromine at room temperature

What happens to density and darkness in group 7
Increases down the group
How does electronegativity change throughout group 7
Decreases Down the group
How does melting point and boiling point change throughout group 7
Melting point and boiling point increase down the group
How does oxidation strength change throughout group 7
Oxidation strength decreases down the group eg fluorine strongest oxidising agent
Can halogens react with metal halides
The halides are displaced if the displacing halogen is a stronger oxidising agent
What are halides
Halogen ions
What is a use of halides
A reducing agent
