Is there removal of second electron difficult in alkali metals?(a) Yes(b) No(c) Maybe(d) Cannot sayThis question was posed to me in an online interview.This key question is from s-Block Elements topic in portion s-Block Elements of Chemistry – Class 11

Answer»

The correct answer is (a) Yes

The best I can explain: The first IONIZATION enthalpy of alkali METALS is the lowest among the elements in their respective periods and increases on moving down the Group. The SECOND ionization enthalpies of the alkali metals are very high because by RELEASING an electron, ions REQUIRE noble gas configuration, so removal of the second electron is difficult.
