Lithium the first element of group 1 differs from the rest of the elements of the group in many repects. This anomalous behavious of Li is due to
(i). Very small size of its atom and ions
(ii). High polarizing power (i.e., charge/radius ratio) of `Li^(o+)` ion
(iii). Relatively high electronegativity and high ionization enthalpy
(iv). Absence of vacant d-subshell in its outmost shell

Anomalous behaviour of lithium is due to I. exceptionally small size of its atom. II. High polarising power. III. High e/r ratio. Choose the correct option.

Carbon, the first member of group 14 , shows an anomalous behavior because of (i) its exceptinally small atomic and ionic size (ii) its higher electronegativity (iii) its higher ionization enthalpy (iv) the absence of vacant d -orbitals in the valence shell

The first element of a group differes from its congeners, i.e other members of the group in many ways. These difference may be due to the following i) Small size of atom and ion ii) High electronegetivity iii) Non-availability of low lying d-orbitals The first element of a group shows resemblance with the second element of the adjacent group on the right. This is known as diagonal relationship Metal (M)+ N_(2) rarr "Nitride" underset("hydroysis")overset(H_(2)O)rarr NH_(3) . Metal (M) can be

Fluorine the I^(st) member of group 17^(th) differs from the other members of the group in many respects due to the following reasons. (i) Small size (ii) Hight EN (iii) absence of 'd' orbitals (iv) its Delta H dissociation in molecular form of X_(2) is the least. The most basic among the following

The first element of group different form its congeners, i.e. other members of the group in many ways. These differences may be due to the following: i. Small size of atom and ion. ii. High electronegativity. iii. Non-availibility of low lying d-orbitals. The first element of a group shows resemblence with the second element of the adjacent group on the right. This is known as diagonal relationship. Lithium exhibits many physical and chemical similarites with magnesium. The reason is:
