Chemistry unit 2 query

[Aahmsil]

Exams are around the corner and I was flicking through the Chemistry AS revision guide when I came across this:

"When electrons are shared, the situation is more stable than when there are two separate atoms (four attractive forces between positive nuclei and negative electrons instead of two)".

I'm afraid I didn't quite understand that statement. I may come off as thick but I'd rather be made to look foolish for a few minutes than live in foolish ignorance. So, can anybody clarify what these four/two attractive forces are? I'll be very grateful.

Thanks in advance!
