The meaning of ATOMIC NUMBER is an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines the place of the element in the periodic table.
2010 5 12 The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present . The number of protons determines how many electrons surround the nucleus, and it is the arrangement of these electrons that
