The mass number of an atom is calculated by adding the number of protons and neutrons together. Electrons do not contribute significantly to the mass number because their mass is very small compared to protons and neutrons.
In this case, you have:
- Protons = 8
- Neutrons = 10
So the mass number can be calculated as:
\[
\text{Mass number} = \text{Number of protons} + \text{Number of neutrons} = 8 + 10 = 18
\]
Therefore, the mass number is **18**.
