name the element wsith the atomic number z= 15 and the atomic mass number 31.

How many electrons does the neutral of this lement have?

How many neutrons does the neutral atoms of this element have?

I know the element with the atomic number of 15 and atomic mass of 31 is phosphorus.
But how do u do the other part?
