The hybridization on the carbon in the methane molecule below is referred to as

hybridization. The

angle of each $H-C-H$ angle, with

carbon as the vertex and the two rays represented by the two $C-H$ bonds, is $109\mathrm{.}5.$ The

overall geometrical shape of the molecule is referred to as a

$.$ The sigma

$()$ bond between the hydrogen and carbon atoms is formed by the overlap of a$/$an $"$

$"$ orbital and a$/$an $\text{'}$

$\text{'}$ orbital $($end on$),$ respectively.
