Which of the following does not illustrate the anomalous
properties of lithium?
(a) The melting point and boiling point of Li are
comparatively high
(b) Li is much softer than the other group I metals
(c) Li forms a nitride Li₃N unlike group I metals
(d) The ion of Li and its compounds are more heavily
hydrated than those of the rest of the group
Answers
Explanation:
Similarities of lithium with magnesium and dissimilarities with that of the other members of the group
Lithium is a very strong element and is equally strong as magnesium.
Li forms Li_3NLi
3
N with nitrogen.
It has high melting and boiling points. The boiling point of lithium is 13301330 degree centigrade that is comparable to that of magnesium which is 11001100 degrees.
Due to small size, the lithium atom has high ionization energy. Hence, it remains inactive to dry air, slowly reactivity with water, liquid bromine and forms a highly stable hydride unlike other alkali metals.
