Question

Ip3>ip2>ip1 explain with switable example

Answer 1

suppose A is an metal

metals IP is low

naturally ip1 will be low

after donating it's electron it will form A+ ion

now A already donated it's electron therefore it will not be easy to remove it's second electron.To remove it some extra heat will be required than it is normally required.

Thats why ip2 is greater than IP1

same reason. for ip3


HOPE THIS HELPS U :-P
