Lewis structure must be drawn for methane. Concept Introduction : Methane is a molecule with formula CH 4 . C is the central atom which is a p block element belonging to group 14. Lewis structure can be determined from the valence electrons of a central atom. Total electron pairs will be: T = ( V + 1 × n + a − c ) 2 Where V, n, a and c are valence shell electrons of central atom, number of monovalent atoms attached, anionic charge, cationic charge respectively.
