Answer :

Considering the definition of atomic number and atomic mass, the number of subatomic particles contained in nitrogen are:

  • the number of proton is 7.
  • the number of neutrons is 7.
  • the number of electrons is 5.

Subatomic particles

All atoms are made up of subatomic particles: protons and neutrons, which are part of their nucleus, and electrons, which revolve around them. Protons are positively charged, neutrons are neutrally charged, and electrons are negatively charged (electrons).

Atomic number

The atomic number is the total number of protons that make up the atomic nucleus of a given chemical element.

Mass number

The mass number indicates the total number of particles in the nucleus. That is, the mass number is the sum of the number of protons and the number of neutrons in the atomic nucleus:

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

Neutral atom

By definition, atoms have no electrical charge. This means that there must be a balance between positively charged protons and negatively charged electrons. That is, atoms have the same number of protons and electrons in a neutral atom.

Number of protons, neutrons and electrons in Nitrogen

The atomic number of nitrogen is 7. This means that the number of proton in the nitrogen is 7.

On the other hand, the nitrogen ion has a mass of 14. Then, considering the definition of atomic mass:

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

14= 7 + number of neutrons

14 - 7= number of neutrons

7= number of neutrons

Then, the number of neutrons in the nitrogen is 7.

If it were a neutral atom, the number of electrons would be 7. But since the charge of the ion is +2, the number of electrons will be calculated as:

Charge = Number of proton – Number of electrons

+2 = 7 – Number of electrons

2 – 7 = – Number of electrons

–5 = – Number of electrons

(-5)÷(-1)= Number of electrons

5= Number of electrons

Then, the number of electrons in the nitrogen is 5.

In summary, the number of subatomic particles contained in nitrogen are:

  • the number of proton is 7.
  • the number of neutrons is 7.
  • the number of electrons is 5.
