Fill in the blank with the most appropriate option given below.

We should give everyone training in citizenship, but we have______this aspect till now.

Two elements $\mathrm{A}$ and $\mathrm{B}$ have electronegativities $1.2$ and $3.0$ respectively. The nature of bond between $\mathrm{A}$ and $\mathrm{B}$ would be

Match List I with List II

For the molecules $\mathrm{LiF},{\mathrm{N}}_2,{ \mathrm{K}}_2\mathrm{O}$ and ${\mathrm{ClF}}_3,$ what is the correct arrangement of bonds in order of increasing ionic character?

Assuming $\mathrm{AB}$ is an ionic compound and ${\mathrm{r}}_{\mathrm{c}}, {\mathrm{r}}_{\mathrm{a}}$ are the ionic radii of ${\mathrm{A}}^{+}$and ${\mathrm{B}}^{-}$respectively. The lattice energy of the compound $\mathrm{AB}$ is proportional to:
