IONIC BONDING


Ionic bonding is formed between metals and non-metals.  

In this figure, the Sodium atom transfer 1 electron to the Chlorine atom to form full valance shells to form an electronic configuration of 2.8 and 2.8.8 respectively. 

In this figure, the Magnesium atom is 2+ while the Chlorine atom is 1-, thus the Magnesium is able to transfer its 2 electrons to 2 Chlorine atoms to obtain an electric configuration of 2.8 and 2.8.8 respectively.
























COVALENT BONDING


Covalent bonds are formed between atoms of non-metal.

An example of covalent bonding is shown in the diagram where atoms share their electrons to form a complete shell.
