Ch4 3d Model. Valence shell electron pair repulsion. Methane the carbon atom central to the methane molecule has 4 valence electrons and thus needs 4 more electrons from four hydrogen atoms to complete its octet.
Methane ch 4 lewis and three dimensional structures tetrahedral 3 dimensional view of ch 4 chemistry home dr. The vapors are lighter than air. Methane has 4 regions of electron density around the central carbon atom 4 bonds no lone pairs.
The resulting shape is a regular tetrahedron with h c h angles of 109 5.
