Ionic bonding
Non directional bond- strength of bond equal in all directions
Conducts electricity when MOLTEN or in SOLUTION(aq)
High melting point and boiling point hard solids
Covalent bonding
The sharing of electrons
Covalent bonding is directional. The strength of the bond is in one direction
Covalent structures are low melting point solid, liquids and gases
They tend not to be soluble in water and have poor electrical conductivity
The outer shell of hydrogen can only contain a max of two electrons (1s orbital) The electrons are equally shared between the hydrogen's
