Assertion :Zinc does not show characteristic properties of transition metals. Reason: In zinc outermost shell is completely filled.
Assertion: Be and Al have similar properties.
Reason: Be2+ and Al3+ have nearly the same charge/volume ratios and similar polarising power.
Assertion
Lithium sulphate does not form alums.
Reason
Li+ is too small to form a stable lattice required for double-salt/alum formation.
