Answer:

Since everything has a mass even an atom so atomic mass is always a whole number ie starting from 0.It can never be negative. Answer: The mass number of any element represents the total number of protons( positively charged particles) and neutrons( neutral particles)together present in the nucleus of the given atom.

Answer:So, the atomic number is always a whole number because there must always be a whole number of protons in a nucleus. In other words, there can never exist fractions of a proton. The atomic mass number is always a whole number for the same reason: protons and neutrons always come in single units, not in fractions.
