Web10 jun. 2014 · Expert Answer Because of the extra stable half-filled p orbitals electronic configuration and smaller size, the ionisation enthalpy of the group 15 elements is much greater than that of group 14 elements in the corresponding periods. Answered by 10 Jun, 2014, 11:01: AM Concept Videos Web20 apr. 2024 · here p- orbital of group 13 has only one electron so, it can easily remove from its isolated form. while s- orbital of group has two electrons( full filled orbital). element is in stable from, so higher amount of energy required to remove an electron. that's why ionisation energy of group 2 is higher than ionisation energy of group 13 .

WebAnswer: D. Solution: Since the valence shell of the elements in group 17 has seven electrons, their general electrical configuration is ns 2 np 5, or ns2np2 x 〖 np 〗2 y 〖 np 〗1 z,, where n=2 to 6 . As a result, they have one less electron than the nearby inert gas configuration. So, option D is the correct answer. Q3.
