We’re being asked to determine the **formal charge of chlorine** in **ClO _{4}^{–}**.

**To do so, we need to do the following steps:**

*Step 1:* Determine the central atom in this molecule.

*Step 2:* Calculate the total number of valence electrons present.

*Step 3:* Draw the Lewis structure for the molecule.

*Step 4:* Calculate the formal charge for the indicated atom.

Recall that the formula for the ** formal charge** is:
