Metals give up electrons to become cation or anion

Metals usually become cations since electrons are negatively charged and when they are lost there are more protons than electrons making a positive net charge in the atom.  (cations are positively charged ions while anions are negatively charged ions)

I hope this helps.  Let me know if anything is unclear.

Metals give up electrons to become cations , I just remember this by " Make Coins" like "Metals and Cations"

Fine out you self hx
