The correct order of melting points of the following salts is $LiF$ $(I)$,$LiCl$ $(II)$,$LiI$ $(III)$.

Write the favourable factors for the formation of ionic bond.

The electronic configurations of four elements $L$,$P$,$Q$,and $R$ are given in the brackets:
$L(1s^2, 2s^2 2p^4); Q(1s^2, 2s^2 2p^6, 3s^2 3p^5)$
$P(1s^2, 2s^2 2p^6, 3s^1); R(1s^2, 2s^2 2p^6, 3s^2)$
The formulae of ionic compounds that can be formed between these elements are:

Elements $X$ and $Y$ have $2$ and $6$ electrons in their valence shells,respectively. If they combine,what will be the possible formula of the compound formed?

An ionic compound $A^{+} B^{-}$ is most likely to be formed when

Among the bonds formed by a chlorine atom with atoms of hydrogen,chlorine,sodium,and carbon,the strongest bond is formed between:
