The catenation property of elements decreases down the group in the periodic table, which explains why sulfur exists predominantly as S8 molecules, while oxygen exists as O2. This phenomenon is attributed to the stronger bonding capabilities of oxygen due to its smaller atomic size and higher electronegativity compared to sulfur. Additionally, the molecular structure of sulfur allows for the formation of larger cyclic structures like S8, whereas oxygen's diatomic form is favored due to its double bond stability.

P4 vs. N2?Dragosagaragarwal said:We know that catenation property decreases down the group...
Then why oxygen exist as O2 molecule while sulphur exist as S8 molecule
