उत्तर
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
