Give reasons:
Iron has higher enthalpy of atomisation than of copper

Give reason : Iron has higher enthalpy of atomisation that of copper.

Define enthalpy of atomisation.

Give reason for the folloiwng : (a) E_("value")^(@) for Mn^(3+)//Mn^(2+) couple is much more positive than that of Fe^(3+)//Fe^(2+) couple. (b) Iron has higher enthalpy of atomization then that of copper. (c) Sc^(3+) is colourless in aqueous solution whereas Ti^(3+) is coloured.

The higher enthalpy of atomisation can be due to :

Explain why Be has higher enthalpy of ionisation than B.

Enthalpy of atomisation is lowest in

Transition elements have higher enthalpy of atomisation than alkali metals due to
