Is my laptop compatible with an i3 processor

what slot does your mobo have?

am not sure this is all new to me,

no

Slot doesn't matter, i3 is not s775.

Perhaps you should consider turning your Caps Lock key off, it doesn't make you look intelligent by any means.

But no, you cannot do that at all. It's an entirely different socket; you'd need to buy a new laptop to get an i3 processor with it.

no, two completely different sockets

No, even you wish it can.
