Which student’s responses are correct?

Answer 1

Student #2: Protons determine the atomic number, and valence electrons show what period the element is in, hope this helps :)

Answer 2

The student that response should be correct is student 2 where there is protons and valence electrons.

Which student’s responses are correct?

So here the proton measures the atomic number and on the other hand, valence electron represents the period where the element is in.

hence the last option is correct.
