The mass of the atom is a unit called the atomic mass unit \(\left( \text{amu} \right)\). One atomic mass unit is the mass of a proton, or about \(1.67 \times 10^{-27}\) kilograms, which is an extremely small mass.

SpletB. Mass Number Equals Protons plus Neutrons Each atom also has a mass number, denoted by the symbol A. The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in any atom is its mass number minus its atomic number. SpletThe number of protons and neutrons combine to give us the mass number of an atom. It is represented using the letter ‘A.’. As both protons and neutrons are present in the nucleus of an atom, they are together called nucleons. For example, an atom of carbon has 6 protons and 6 neutrons. Thus, its mass number is 12.
