Question

Which one of the given statements is incorrect in relation to ionization enthalpy?(a) Ionization enthalpy increases for each successive electron. (b)The greatest increase in ionization enthalpy is experienced on removal of electron from core noble gas configuration. (c) End of valence electrons is marked by a big jump in ionization enthalpy. (d) Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value.

Answer 1

Answer:(d) Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value.

Explanation:

Lower n value means

Shells near to nucleus.

Near the nucleus force of attraction is higher .

As no. Of shells increases size increases and hence force decreases..

So its easier to remove electron for outer shells or higher value of n..than inner shells or lower n value

Hope you got the bunch!
