Tyler Miller explains this better than I've seen in a while...and that appreciation is coming from someone who would still be an undergraduate if he had to take one more chemistry class. Thanks Tyler!
On a less serious note, when I first read the topic question I was reminded of an old joke:
Two hydrogen atoms walk into a bar...
One says, "I've lost my electron".
The other responds, "Are you sure?"
The first replies, "Yes. I'm positive!"
When two elements love each other very much, they come together to form a compound.
Sorry, I'm not helping.
