What is the number of protons and electrons in gold?

Explanation:
Gold’s atomic number is 79, which is the number of protons in its nucleus. In a neutral atom, the number of electrons equals the number of protons, so there are also 79 electrons. So the counts are 79 protons and 79 electrons. The other numbers would correspond to other elements, not gold, unless the atom is ionized.
