type the correct answer in each box. the atomic number of sodium (na) is 11. the element phosphorous (p) is the fourth element to the right of sodium in the periodic table. the atomic number of phosphorus is . it has zero charge because it has electrons.

type the correct answer in each box. the atomic number of sodium (na) is 11. the element phosphorous (p) is the fourth element to the right of sodium in the periodic table. the atomic number of phosphorus is . it has zero charge because it has electrons.

Answer

Explanation:

Step1: Determine atomic number of phosphorus

Add 4 to sodium's atomic number. $11 + 4=15$

Step2: Recall electron - atomic number relationship

For a neutral atom, number of electrons = atomic number. So phosphorus has 15 electrons.

Answer:

15; 15
