The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
in order to obtain the mass number of an atom you must get the number of neutrons + the number of protons which = the mass number !!!hope this helped!!! :)
The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.

No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
It is equal to the difference between atomic number and Atomic Mass number. A+
atomic mass is contributed mainly by protons and neutrons. it is the mass of an atom. atomic number on the other hand is contributed by protons and is equal to the number of protons in the atom
no, the mass number is number of protons in an atom, plus the number of neutrons.
