A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms — CH 3. The Lewis structure of ammonia, #NH_3#, would be three hydrogen atoms bonded to a nitrogen atom in the middle, with a lone pair of electrons on top of the atom. Usually try to draw the most symmetrical structure with the atom of least electronegativity in the center. Determining Formal Charge Although we know how many valence electrons are present in a compound, it is harder to determine around which atoms the electrons actually reside. A Lewis structure (or electron-dot formula) is a two-dimensional structural formula showing the arrangement of electrons around atoms in covalently bonded molecules—i.
