Indicate the nature of bonding in diamond.

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

What happens when naphthalene balls are put inside kerosene?

What is the proportionality between $(I)$ Bond length and size of atom, and $(II)$ Bond length and multiplicity of bond, respectively?

The $X-X$ bond length is $1.00 \mathring{A}$ and $C-C$ bond length is $1.54 \mathring{A}$. If $EN$ of $X$ and $C$ are $3.0$ and $2.0$ respectively,the $C-X$ bond length is likely to be ............ $\mathring{A}$.
