covalent bonding 

When non metal atoms share pairs of electrons, they form covalent bonds. These bonds between atoms are strong. The shared electrons aim to fill the outer shell. 

• Non metals
• H-H
• strong 
• to become stable 

molecular- water- doesnt conduct elecricity as there are no free electrons- low melting point as no bonds need to be broken. 

Ionic bonding 

When atoms form chemical bonds by transferring electrons, they form ions. Atoms that lose electrons become …
