Ionic Bonding

Ionic Bonding

Ions are electronically charged particles formed when atoms lose or gain electrons
1. This loss or gain leaves a complete highest energy level, so the electronic structure of an ion is the same as that of a noble gas
Metal atoms and non-metal atoms go in opposite directions when they ionise
1. Metal atoms - lose the electron, or electrons, in their highest energy level and become POSITIVELY charged ions
2. Non-metal atoms - gain an electron, or electrons, from other atom become negatively charged ions
There is a quick way to work out what the charge on an ion should be
1. The number of charges on an ion formed by a metal is equal to the group number of the metal
2. The number of charges on an ion formed by a non-metal is equal to the group number minus eight
When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions
