Question

Plzz I will mark u the brainiest.

The electronic configuration of Cr⁺³ .

Answer 1

It's Ar 3d3

As first 2 electron are removed from 4s orbital due to lower energy required...

Then 1 electron is removed from 3d orbital...

Thanks.

Answer 2

The atomic Number of cr is 24 but it is given that chromium lossed three electron. so, number of electron in the valence shell reduced from 6 to 3

electronic configuration is 1s^2,2s^2,2p^6,3s^2,3p^6,4s^2,3d^1
