The atomic number of gold is, 79. The chemical symbol of gold is, Au.
Explanation :
Atomic number : It is equal to the number of protons or electrons.
Atomic number = number of protons = number of electrons
Mass number : It is defined as the sum of number of protons and number of neutrons.
Number of neutrons = Mass number - Number of protons
As we know that:
