Atomic number = number of protons or electrons (in a neutral atom)
Mass number: sum of protons and neutrons
The mass number is bigger.
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
The bigger number (Atomic mass) is the amount of protons (=same amount of electrons unless specified) and nutrons in an atom. The smaller number (atomic number) is the amount of protons only
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
You can't change the mass number of an atom because the mass number is the number of protons which is the atom's atomic number I hope this helped :)
Mass number!:)
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.

The number of neutrons in an atom can affect the atomic mass of an atom.
the mass number is number of protons in an atom, plus the number of neutrons.
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
