Element With 33 As Atomic Number

The sum of the atomic number Z and the number of neutrons N gives the mass number A of an atom. Since protons and neutrons have approximately the same mass (and the mass of the electrons is negligible for many purposes) and the mass defect of nucleon binding is always small compared to the nucleon mass, the atomic mass of any atom, when expressed in unified atomic mass units (making a quantity. The mass number of a nuclide is the sum of the number of protons and the number of neutrons in the atomic nucleus (the number of protons is the atomic number). The mass number is noted as a superscript for the symbol, for example, 206 Pb. The notation Pb-206 is also used. Define atomic number.
