Explanation For silicon, the atomic number ( Z ) is 14. So, the number of protons is 14. Calculate the mass number ( A ) as follows: Mass number = Number of protons + Number of neutrons = 14 + 14 = 28 The number of protons is equal to the number of electrons, which implies that the charge is zero. For sulfur, the atomic number ( Z ) is 16. So, the number of protons is 16. For a neutral molecule, the number of electrons is equal to the number of protons. Sulfur has a charge of −2, which means it has gained two electrons. So, the number of electrons is 18. Calculate the number of neutrons as follows: Mass number = Number of protons + Number of neutrons 32 = 16 + Number of neutrons Number of neutrons = 32 − 16 = 16 For copper, the atomic number ( Z ) is 29
