How do we know that the formal charge of CH2 with one bond and one electron pair is -1?

If you draw out the whole molecule, you'll see that for a non-central Carbon atom that is attached to the central Carbon with a single bond, the Carbon has a FC=4-(2+3)=-1. The -1 FC of CH2 is based off of the Carbon atom. (The two H atoms each have a FC of 0)
