The mass number of an atom is the sum of its protons and neutrons.
For the gold atom in question, which has:
- 79 protons
- 118 neutrons
The mass number is calculated as follows:
Mass number = Number of protons + Number of neutrons
Mass number = 79 + 118
Mass number = 197
So, the correct answer is **c) 197**.
