Solution

Solution Steps

Step 1: Identify the Element

The image shows an atom with 8 protons (p⁺), 8 neutrons (n⁰), and 8 electrons (e⁻). The number of protons determines the element. An atom with 8 protons is oxygen.

Step 2: Determine the Atomic Number

The atomic number is the number of protons in the nucleus of an atom. For this atom, the atomic number is 8.

Step 3: Determine the Mass Number

The mass number is the sum of protons and neutrons in the nucleus. For this atom, the mass number is 8 (protons) + 8 (neutrons) = 16.
