Question

A sudden jump between the values of IE2 and IE3: of an element is
associated with the configuration​

Answer 1

Answer:

It is associated with group 2 elements with a configuration of ns2.

Explanation:

• Alkaline earth metals lose 1 electron to form a configuration of alkali metals without much increase in its IE.

• Then it readily loses one electron to get noble gas configuration as it is highly

stable.

• After achieving noble gas configuration, the element hesitates to give electron as it is highly stable.So we need large amount of energy to make the element lose an electron.Thus the IE will be very very high

Hope it is clear.
