Answer:
Metals form positive ions or 'cations' while non-metals typically form negative ions or 'anions'.
Step-by-step explanation:
Metal atoms lose electrons, this causes them to gain an overall positive charge due to there being more protons than electrons.
This means they form positive ions.
Most non-metals gain electrons, this causes them to gain an overall negative charge due to there being more electrons than protons.
This means they form negative ions.
