the `Ca^(2+)` ion has a noble-gas electron configuration, and the `Cd^(2+)` ion, an 18-electron configuration of its outer shell

D

all of the above are correct

Text Solution

    In an ionic bond, the cation tends to polarize the electron cloud of the anion by pulling electron dens towards itself. This causes development of covalent character in the ionic bond because the electron dens gets localised in-between the nuclei. The tendency of the cation to bring about the polarization of the anion expressed as its polarizing power. The ability of ion to undergo polarization is called its polarisability. The polarising power of a cation or an anion is decided on the basis of Fajans' rules. Arrange the following species in decreasing order of polarising powers: Ag^+ , Tl^+ , Na^+
