when we move down the group we come to know..
sheilding effect between electrons because of increase in no.of shells and electrons.
and cause of shielding it takes less energy to remove or add a electron in outermost shell.....
because shelding effect decrease the efect of nuclear charge on outer atoms......
hope it will help u..mak as brainliest..i need it...
