HideShow resource information

Ionic bonding means: TRANSFERRING ELECTRONS.

Some atoms lose or gain electrons to form charged particles (called ions) which are then strongly attracted to one another <-- Opposite charges attract, + and -.

All atoms want their outer shells to be full and happy like Group 0/8, the Noble Gas group. This means that if an outer shell of an atom has only one electron, it would want to get rid of it. Likewise, a nearly full shell wants to gain an electron.
