Question

Write the electronic configuration of Fe 2+ ion?

Answer 1

26----------atomic no

2,8,8,8 is the electronic configuration of Fe 2+ ion

as it looses 2 electrons

Answer 2

Atomic No. of Fe == 26......... Its electronic configuration = 1s^2 2s^2 2p^6 3s^2 3p^6 3d^6 4s^2 .......... Fe 2+ means it looses two electrons, therefore its electronic configuration will be ===>> 1s^2 2s^2 2p^6 3s^2 3p^6 3d^6
