I think the valence electrons is 4 and the shell is 6 but I'm not 100% sure if that s right. If it is can someone explain to me why? It would really help me for a big test tomorrow.

Yes you are absolutely right.

First of all, it's shell 6 because lead, Pb 82 is located on the 6th row.

It has a valence electron of 4 because if you count from left to right, it happens to be the forth one.

Note: transition metals (columns 3-12) are often skipped because they are unpredictable.

So skipping the transition metals, start out with
Cs, 55  -----> 1 VE
Ba, 56  -----> 2 VE
Ti, 81   -----> 3 VE
Pb, 82  -----> 4 VE
