Question

The second ionisation potential of a given atom is 12.08V. the ionisation potential must be

A) 12.08V

B) 13.6V

Answer 1

Dear Student

2nd ionization potential is the energy needed to remove a second electron from each ion in 1 mole of gaseous 1+ ions to give gaseous 2+ ions. When the first electron is removed from an element,its effective nuclear charge increases. Once,the effective nuclear charge increases,the hold of nucleus over its outermost electrons increases.
So that the ionization potential will be less than the 2nd ionization potential.but while you looking to the options there no value which is smaller than 2nd ionization potential
So dear student make sure that you have uploaded all the options.
THANK YOU.
