If neon has an atomic number of 10 and an atomic mass of 20, it has neutron(s) in its nucleus

The correct answer is 10

Explanation:

To begin with, an atom always contains neutrons and protons located in the nucleus along with neutrons that orbit it. In this context, the atomic number represented by Z is equivalent to the number of protons or positively charged particles. This means if neon has an atomic number of 10 the number of protons is 10. On the other hand, the atomic mass is mainly defined by the number of protons and neutrons. This implies, in the case presented, the number of neutrons in the neon atom is 10 considering the atomic mass 20 (number of protons and neutrons) - atomic number 10 (number of protons) = 10 neutrons.
