To determine the electrical charge of the atom, we can use the following formula:
\[
\text{Charge} = \text{Number of protons} - \text{Number of electrons}
\]
Given that the atom has:
- 18 protons
- 22 electrons
We can calculate the charge as follows:
\[
\text{Charge} = 18 - 22 = -4
\]
Thus, the atom has an electrical charge of -4.
The correct answer is **B. -4**.
