검증된 단계별 안내1
Identify the central atom in methane (CH_4), which is carbon (C).
Recall that carbon has 4 valence electrons and needs 4 more electrons to complete its octet.
Each hydrogen atom has 1 valence electron and needs 1 more to complete its duet.
In the Lewis dot structure, carbon forms single covalent bonds by sharing one electron with each hydrogen atom.
Since there are 4 hydrogen atoms, carbon forms 4 single covalent bonds with the hydrogen atoms.
