Solution

Formation of methane molecule:

Atom Electronic configuration Nearest noble gas To attain stable
electronic
configuration of
nearest noble gas
Carbon `""_6^12C [2,4]` Neon [2,8] Carbon needs four
electrons to
complete the
octet
Hydrogen `""_1^1H[1]` Helium [2] Hydrogen needs
one electron to
complete the
duplet

One atom of carbon shares four electron pairs, one with each of the four aoms of hydrogen

Concept: Periodic Properties - Electron Affinity
