Reduction

What is the term used when a metal loses oxygen

400

 A polystyrene cup.

What should be used to contain the solution when investigating an energy change?

500

As you go down group 7 the atoms get bigger because they have more electron shells, this mean the attractive force of the nucleus is weak and so it is harder to gain an extra electron.

What is the reason group 7 reactivity decreases down the group?

500

Each carbon atom forms three covalent bonds with three other carbon atoms, forming layers that have no covalent bonds between them.
