Neon has 8 valence electrons in the outermost shell and Methane also has 8 valence electrons in the outermost shell.
Neon ( Noble gas )
The atomic number is 10, 1s2, 2s2, and 2p6.
Eight total valence electrons in the outermost shell (2s2,2p6). Since neon's octet is already complete due to having 8 valence electrons in its outermost shell, it lacks the orbitals necessary to form covalent bonds and does not have any bonding pairs.
Four of its pairs are non-bonding. Since they won't form any bonds, all of the electrons will be counted as non-bonding pairs (1 pair equals 2 electrons
CH4 (Methane) (Methane) Eight valence electrons total. It has four pairs of bonds. 0 (because there are no lone pairs) non-bonding pairs.
