Define atomic number and mass number.

. A specific atom of molybdenum has an atomic number of 42 and a mass number of 96. The standard atomic weight is the average mass of an element in atomic mass units amu. The mass number of an atom also gives its atomic mass.

The number of protons that a chemical element has in its centre nucleus is called atomic number. B Number of 0 n 1 W N. The number of protons in the nucleus of an atom.

To calculate the numbers of subatomic particles. It means the mass number of an atom depends on the number of protons and neutrons present in the nucleus of that atom. Of protons No.

So on the first one the mass number is 12 indicating that the total number of protons and neutrons is 12. The number of protons plus the number of neutrons in a nucleus. This is because the atomic mass of an atom is numerically equal to the mass number.
