Identify the number of protons and electrons in the atom. Here, the atom has 15 protons and 18 electrons.
Recall that the charge of an atom is determined by the difference between the number of protons (positive charges) and electrons (negative charges).
Calculate the net charge by subtracting the number of protons from the number of electrons: \(\text{Charge} = \text{Number of protons} - \text{Number of electrons}\).
Substitute the values: \(\text{Charge} = 15 - 18\).
Interpret the result: if the charge is negative, the atom has gained electrons and is negatively charged; if positive, it has lost electrons and is positively charged.
