Which one will have the highest 2nd ionisation energy?(A) 1s2 282 2p 3s(B) 1s 2s 2p+(C) 1s2 2s2 2p(D) 1s2 2s 2p 3s? |

Answer» The element with electronic configuration 1s 2 2s 2 2p 6 3S 1 will have HIGHEST second ionization enthalpy. 1s 2 2s 2 2p 6 3s 1 loses one electron to form 1s 2 2s 2 2p 6 . It is stable electronic configuration of noble gas NE. Removal of second electron will require large amount of energy as it will break stable noble gas electronic configuration. |
