@euch27 isotopes have different mass numbers because the number of neutrons found in the nucleus differs (that is what makes them isotopes).

@Elvishrain No DUDE, i'm 18, not some frumpy old dad, and I can easily type your stupid text talk, but I enjoy writing complete words so I can avoid looking like a complete tool. which is "wat u r. lulz I trlld u so hrd" - my point exactly. And what the fuck does "where do u live in dude" even mean? Even your attempt at a complete and normal sentence ends in a fail.

I really don't understand what YOU'RE trying to say. You'll never make it in life if you can't type complete words.
