List three properties of lithium in which it differs from the rest of the alkali metals.

Write two properties of lithium carbonate in which it differs from other alkali metal carbonates.

Name first three alkali metals

Choose the figure which is different from the rest.

Lithium is the hardest alkali metal.

Which group differs from rest of the three regarding symmetry?

Both alkali metals and alkaline earth metals are s- block elements. They resemble each other in many respects but still there are certain dissimilarities in their properties due to different number of electrons in the valence shell, different atomic radii, ionisation enthalpy, electronegativity, etc. Like lithium, Be also differs from rest of the alkaline earth metals on account of its small atomic size and high electronetativity. Be^(2+) ion is very small and exerts a high polarising effect on any anion associated with it. Which of the bicarbonate does not exist in solid state?

Write two properties of the alkali metal hydrides.
