A carbon iota can bond with four other iotas and is just like the four-hole wheel, whereas an oxygen iota, which can bond only to two, is just like the two-hole wheel.

Each element tries to achieve stability by forming a noble gas configuration (2 or 8 valence electrons)

Carbon has 4 valence electrons, achieving stability requires 4 more electrons

Hydrogen has 1 valence electron, achieving stability requires 1 more electron

Carbon and hydrogen bond covalently by sharing their electrons so that they become stable (carbon binds 4 hydrogens) to form CH₄ (methane)
