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

Define the mass number of 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

The Atomic Number of an element is equal to:AThe mass of the atom.BThe number of neutrons.CThe number of protons.DThe number of protons + neutrons.

An atom's mass number is determined by the number of (1 Point)nucleons in its nucleusneutrons in its nucleusprotons in its nucleuselectrons in its nucleus

ANswer only forever An atom's mass number is determined by the number of (1 Point) nucleons in its nucleus neutrons in its nucleus protons in its nucleus electrons in its nucleus
