Who am I?

Sodium I am stored in oil I react with water to form an alkali compound I burn with an orange flame I am more reactive than lithium

Chlorine I am very reactive I am a gas at room temperature I am a yellow green gas I was used during the war to poison people I am used to keep water clean I am found in Group 7

Potassium I am stored in oil I react with water to form an alkali compound I burn with an lilac flame I am more reactive than sodium DEMO – LOVE HEARTS (Protons), PARMA VIOLETS (Neutrons) and SKITTLES (electrons)

Bromine I am liquid at room temperature I am orange/brown colour I have to be used in a fume cupboard I am more reactive then iodine

Iodine I am solid at room temperature I can be used during surgery and to clean wounds I am found in seaweed When I am a gas I am purple I am in group 7
