Answer

Explanation:

Step1: Determine atomic number of phosphorus

The atomic number increases by 1 for each element to the right in the periodic - table. Sodium has an atomic number of 11. Phosphorus is 4 elements to the right of sodium. So, the atomic number of phosphorus is (11 + 4=15).

Step2: Relate electrons to charge

For a neutral atom, the number of electrons is equal to the atomic number. Since phosphorus has a zero - charge (is neutral), it has 15 electrons.

Answer:

15; 15
