lionization enthalpy:-)
lt is the amount of energy which is required to remove most loosely bonded electron from an isolated gaseous particle.
Change in ionization enthalpy :-)
☆Along period :-
along the period ionization enthalpy increases due to increase in nuclear charge.
inert gases have extra stability so there ionization enthalpy is maximum.
Along group:-
on moving down the group size of atom increases ionization enthalpy decrease due to decrease in force of attraction.
