Verified step by step guidance1
Identify the central atom in the molecule CH4, which is carbon (C).
Recall that an electron group around an atom includes bonded atoms (single, double, or triple bonds) and lone pairs of electrons on that atom.
In methane (CH4), carbon forms four single covalent bonds with four hydrogen atoms.
Since there are no lone pairs on the carbon atom, each bond counts as one electron group.
Therefore, the total number of electron groups around the central carbon atom is 4.
