The bonds in methane are ? because hydrogen and carbon have ? electronegativity. Carbon bonds with four hydrogen atoms because hydrogen has ? valence elctron(s) and carbons had ? valence electrons; so carbon shares ? valence electron(s) with each of the four hydrogen atoms to satisfy the necessary ? valence electrons for carbon and ? for hydrogen to become ?

The bonds in methane are covalent because hydrogen and carbon have similar electronegativity. Carbon bonds with four hydrogen atoms because hydrogen has one valence electron and carbon has four valence electrons; so carbon shares one valence electron with each of the four hydrogen atoms to satisfy the necessary eight valence electrons for carbon and two for hydrogen to become stable.
