How many protons electrons and neutrons does the isotope nitrogen 15 have

The atomic number of N 157

The number of protons is 7

The number of electrons is 7

The number of neutrons is 8

Explanation:

The atomic number of Nitrogen is 7 because Nitrogen has 7 protons.

The seven protons attract 7 electrons in the ground state.

If the atom had fewer or more than 7 protons the atom would not be Nitrogen.

The mass of the atom is the sum of protons and neutron. so

p + n = mass (protons (p) and neutrons (n) both have an atomic mass of one

7 + n = 15 subtract 7 from both sides

7-7+n=15-7

n = 8
