The alkali metals are soft due to-

Oxides and hydroxides of certain metals i.e. _______ [iron (zinc/copper/aluminium/magnesium/ lead] are amphoteric acid react with ___________[acids/alkalis/acids & alkalis] to give salt and water.

Why does the basic strength of the hydroxides of alkali metals increase on moving down the group ?

Assertion: Among hydroxides of alkali metals, LiOH is the weakest base. Reason: Among alkali metals, lithium has the highest ionisation energy .
