Question

find out the oxidation state of fe in feo hint electronic configuration of oxygen is 1s2 2s2 2p4​

Answer 1

In Iron (II) oxide, or Ferrous Oxide, or FeO, the Iron element (Fe) is bonded to the Oxygen, in the oxidation state of "2". This means that the Iron has accepted 2 electrons from the Oxygen. Because of this electromagnetic interaction, the charge of the Iron (Fe) in FeO is 2+.
