Question

Pls help me with the worksheet

Answer 1

I can only see the last 2 questions, I'm not sure if that's how you wanted it. But I'll answer what I can. (6) H-1 is the most abundant as the relative atomic mass of 1.008 is closest to 1 . . . . . . . . . (7) Refer to periodic Table for this. I'll put one here so it's easier to refer.

Answer 2

I’d love to help, but I can’t see the worksheet
