Question

What is Condensed Electron Configuration of O-1 and is it paramagnetic or diamagnetic?

Answer 1

Answer:

The possible oxidation states of element Oxygen(O) are -1 and -2.

The general electron configuartion is 1s² 2s² 2p⁴. It has two unpaired electrons. Then the oxygen can interact with magnetic field so it is paramagnetic in nature.

The electron configuration of the oxidation state of Oxygen O^2- is 1s² 2s² 2p⁶. It follows octate rule, that means the valency shell has total eight electrons and it is stable configuration, Therefore, it is diamagnetic in nature.

But, the oxidation state O^1- has the configuration is 1s² 2s² 2p⁵, so it has one unpaired electron. Therefore, it is paramagnetic in nature.
