atomic number. The number of protons in the nucleus of an atom. In electrically neutral atoms, this number is also equal to the number of electrons orbiting about the atom's nucleus. The atomic number of an element determines its position in the Periodic Table.
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.
