covalent bond 

-2 or more atoms share electrons in order to acheive a full outer shell in order to follow the octate rule(which is to achieve a full outer shell).

- For example CO2, H20 are type of molecules which contain covalent bonds  

Ionic bonds

- opposite charges attract to each other to form AN IONIC MOLECULE

-for example, NaCl (also known as common salt) contains atoms which contain a Na+1 charge and a Cl-1 to it.

-The Na and Cl atoms both are attracted to the opposite charges forming an ionic bond to hold up the giant ionic lattice structure of NaCl

well Lizzie, ionic bonds are bonds which form between oppositely charged ions.

What are ions?

Ions are elements with a charge, for example Mg2+ or O2- etc

These ions dont overlap or anything like that but there bonding is based on attraction and therefore do not link with each otehr but there is a gap between the bonded ions!  These ions have got their charge due to the loss and gain of electrons which i have exaplained on this very recent post:

Covalent bonds:

Covalent bonds is the attraction between the sharder electrons and between the two postive nuclei of the atoms.

Covalent bonds are without any sort of charge but wot they do, is that they are actually very nice so they share their electrons with another atom thus is does not unbalance the charge as it is still neutral. The link i showed has explained this a bit as well.

Covalent bonds are stronger then ionic bonds. Let me give u a example, if we had two people stand next to each other n one was postive and the other negative, then it will be quite hard to break becuz you have to overcome the pull of oppostiely charged ions which requires energy, but covalent bonds are harder! Again imagine two random people standing next to each other, except this time neither was charged and this time they were linking arms. Now which one is harder to break apart, ionic or covalent ====> covalent obviously making it a very strong bond.

This is wot u really need for GCSE, but for a level it gets more complicated, n if u wuld like i culd explain that two u sum time! =D anyway hope i helped!!!!!
