AI Generated Solution

To find the mass number of oxygen and sulfur, we can follow these steps: ### Step 1: Understand the definition of mass number The mass number of an atom is the total number of protons and neutrons in its nucleus. It can be calculated using the formula: \[ \text{Mass Number} = \text{Number of Protons} + \text{Number of Neutrons} \] ### Step 2: Identify the atomic number and number of neutrons for oxygen - The atomic number of oxygen (O) is 8. This means that oxygen has 8 protons. ...
