The mass number is the sum of protons and neutrons in the atomic nucleus.
Mass number = Number of protons + number of neutrons
Mass number = Number of Protons + Number of Neutrons
Number of neutrons = Mass number - Number of protons
Number of neutrons = Mass number - Number of protons
To find the mass number of an atom, you add together the number of protons and neutrons in the nucleus of the atom. The atomic mass listed in the periodic table is the weighted average of the mass numbers of all isotopes of that element.

You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
The mass number doesn't depends on the number of electrons.
