Vedclass · Answer

(B) $1$. Chalcogens (Group $16$ elements) have $6$ electrons in their valence shell.$2$. In their hydrides $(H_2X)$, the central chalcogen atom forms $2$ covalent bonds with hydrogen atoms.$3$. Out of $6$ valence electrons, $2$ are used in bonding, leaving $4$ electrons as non-bonding electrons.$4$. These $4$ non-bonding electrons form $2$ lone pairs.$5$. Therefore, there are $2$ bond pairs and $2$ lone pairs.

What is the number of bond pair of electrons and lone pair of electrons present in the valence shell of chalcogens in their hydrides $(H_2X)$?
