How many protons does an atom of gold have?

There are 79 protons in the nucleus of one Gold atom.

Explanation:

The number of protons of any given atom/element can be determined by the atomic number of the specific element, which is found on the periodic table.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
