The bond formed in a crystal by an anion and a cation is:

An atom of an element $A$ has three electrons in its outermost shell and that of $B$ has six electrons in the outermost shell. The formula of the compound between these two will be

The ionization of $AlCl_3$ in aqueous solution occurs because ........

If the enthalpy of sublimation of $Li$ is $155 \ kJ \ mol^{-1}$, enthalpy of dissociation of $F_2$ is $150 \ kJ \ mol^{-1}$, ionization enthalpy of $Li$ is $520 \ kJ \ mol^{-1}$, electron gain enthalpy of $F$ is $-313 \ kJ \ mol^{-1}$, and standard enthalpy of formation of $LiF$ is $-594 \ kJ \ mol^{-1}$, then the magnitude of the lattice enthalpy of $LiF$ is . . . . . . $kJ \ mol^{-1}$ (nearest integer).
