C4- Ionic Bonding

ions are made when atoms gain or loose electrons
when they do this they gain charged particles called ions
ions can be single atoms or grouped atoms
when they ionise they are trying to get a full outer shell
all atoms in group 1 have 1 electron in the outer shell
they want to get rid of this electron as they will then have a full outer shell
when group 1 elements (sodium, potassium etc) lose and electron they form positive ions
a nearly full shell wants to gain an extra electron
in group 7…
