A. sulfur B. phosphorus C. chlorine D. selenium

Answer 1

The answer for the first question is definitely D. 10, as it is a neutral atom, therefore numbers of p+ and e- are the same.

`s-p-d-f is 2-6-10-14`
What about the next one, the answer is A. sulfur.
I am pretty sure that these answers are correct, you will definitely find them useful.
