Define the mass number of an atom.

The mass number of an atom is defined as: Total number of electrons in an atom Total number of protons, neutrons and electrons in an atom Total number of protons in an atom Total number of protons and neutrons in an atom

How is the atomic mass of an element determined?By adding the number of protons and electronsBy the number of protons in the nucleusBy the number of electrons in the outer orbitalsBy adding the number of protons and neutrons in the nucleus
