Custom Enrichment Module: Astronomy Update for Shipman/Wilson/Todd's Introduction to Physical Sciences (12th Edition) Edit edition. The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. Thus, each proton and neutron has a mass of about 1 amu. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties. The atomic number of gold is 79 and it is indicated by symbol Au. The atomic number equals the number of protons in an atom.
