Becausethe more shells it has around the nucleus (the bigger it is, as electrons account for most of the volume of a shell) the more negative shells 'shielding' the positive nucleus, which means the nucleus cannot remove electrons/attract electrons from other atoms as efficiently.

If an atom has less shells, i.e. is small, the nucleus isn't as far from the outside of the atom/isn't as 'shielded' by many electron shells, and so has a stronger pull on electrons from other atoms.

thanks, also to yasmina, this finally makes sense.

Nice detaild piece of work, isn't too wordy either! Did help clear a few things up for me, so thanks, few spelling mistakes though, but hey, they don't matter :P

Thanx!! Very helpful!! :)
