the number of protons in the nucleus of an atom of a particular element. In a neutral atom, the atomic number equals the number of electrons. See also atom, electron, proton.
Mass number-atomic number = # neutrons. Determining the number of electrons-. The number of electrons in an element can change. For a neutral atom, the number of protons is exactly equal to the number of electrons.So the number of electrons is the same as the atomic number.ass number-atomic number = # neutrons. Determining the number of electrons-. The number of electrons in an element can change. For a neutral atom, the number of protons is exactly equal to the number of electrons.
