formation of ions Flashcards
1
Q
what are ions?
A
ions are charged particles made when electrons are transferred so an atom can have a full outer shell.
2
Q
what happens when metals form ions?
A
they lose electrons from their outer shells to form positive ions (cations).
3
Q
what happens when non-metals form ions?
A
they gain electrons from their outer shells to form negative ions (anions).
4
Q
what groups are most likely to form ions?
A
group 1 & 2 (metals; positive ions)
group 6 & 7 (non-metals; negative ions)
