Summary

Non – metals form
ions.

Group 7 non - metals form
ions because they gain
electron to
ions because they gain
electrons
ions because they gain
electrons
gain a full set of electrons.

Group 6 non - metals form
to gain a full set of electrons.

Group 5 non - metals form
to gain a full set of electrons.
