Reactions of group 1 metals with oxygen The group 1 metals all react in a similar way because They all have one electron in their outer shell

What’s happening when metals & non-metals react? When metals react with non-metals electrons are transferred. Metal atoms Non-metal atoms + ions– ions electrons Ionic compound Atoms get full outer shells by transfer of electrons.

Metals & non-metals When metals react with non-metals electrons are. This forms oppositely charged. These ions attract each other and form ionic substances

What’s happening when non-metals & non-metals react? They SHARE electrons. This forms molecules.
