pi4t: If you don't know, the reason that scores can't normally go below a 3 in character creation (other than racial penalties and suchlike, perhaps?) is that in normal dungeons and dragons stats are generated by rolling 3 6 sided dice and adding them up. There are several variants to that system to ensure you don't get terrible scores, especially in your key stats, but they mostly revolve around that mechanic. In fact, BG uses a variant on the system itself: it rolls 3 dice for all 6 stats, rerolling any that are below minimum requirements for your class, but then lets you reassign the points as you wish. That's my understanding, anyway.

Geoguy's table only shows strength, but it appears that if you replace 'str' with 'dex', 'int', etc in the link it'll take you to the other tables.

AlKim: Yes, racial penalties are applied after you have assigned the points, so it's possible to have a half-orc fighter with an Intelligence score of 1.

As far as I know, having an ability score of 10 means that the person is average in that field, or perhaps slightly fitter than most people (in which case Average Joe would have a score of 8 or 9 in everything); a score of 3 is pretty catastrophic for certain aspects of an individual's life. The half-orc I mentioned earlier would be no more intelligent than an animal, and actually dumber than many of them, which would certainly cause many kinds of social issues.
