Covalent Bond

Vedclass · Answer

(B) Element $B$ has the valence shell configuration $3s^2, 3p^3$,which means it has $5$ valence electrons. It needs $3$ electrons to complete its octet.Element $C$ has the valence shell configuration $3s^2, 3p^5$,which means it has $7$ valence electrons. It needs $1$ electron to complete its octet.Both $B$ and $C$ are non-metals. When two non-metals combine,they share electrons to complete their octets,resulting in the formation of a covalent bond.Therefore,the bond between $B$ and $C$ will be a covalent bond.

The electronic configuration of three elements $A$,$B$,and $C$ are given below. The bond between $B$ and $C$ will be:
$A: 1s^2, 2s^2, 2p^6$
$B: 1s^2, 2s^2, 2p^6, 3s^2, 3p^3$
$C: 1s^2, 2s^2, 2p^6, 3s^2, 3p^5$
