Answer :
Final answer:
An atom of gold with atomic number 79 and mass number 197 contains 79 protons, 118 neutrons, and 79 electrons.
Explanation:
Inside an atom of gold with atomic number 79 and mass number 197, you would find:
79 protons - Protons are heavy particles with a positive charge and are located in the nucleus of an atom. The atomic number of gold determines the number of protons.
118 neutrons - Neutrons are heavy particles with no charge and are also located in the nucleus. The mass number minus the atomic number gives the number of neutrons in an atom.
79 electrons - Electrons are light particles with a negative charge and they orbit around the nucleus. In a neutral atom, the number of electrons is equal to the number of protons.
