The atomic mass of nitrogen is 14.007 and the atomic number is 7 rounding to the nearest whole number what is the number of neutrons in one nitrogen atom

- 14

- 6

- 7

- 4

Mass = #of protons (atomic number) + #of neutrons

So

# of neutrons = mass - #of protons (atomic number)

Therefore

14 (mass) - 7 (#of protons/atomic number) = 7 (#of neutrons)

The answer is c.) 7 neutrons
