Question

Q.12" The ionisation enthalpy also depends upon the electronic configuration of the atom. It has been
observed that pertain electronic configurations are more stable than others. For example half filled and
completely filled shell have extra stability associated with them. Consequently it is difficult to remove
electron from these stable oonfleurations
Answer the following on the basis of the above paragraph
Why the noble gases have highest value of ionisation enthalpies in their respective period?
out of u, Be, Mg, Al, P and ci which have completely flled and half-filled orbitals consequently
large ionisation enthalples
​

Answer 1

Answer:

Noble gases have completely filled orbital configuration.so they have complete octet and extra stability.

So, high ionisation enthalpies

Be and phosphorus have extra stability. so, high ionisation enthalpies
