 The maximum number of unpaired electrons in Fe^3+ is 5. Explanation: Click here 

    In the ground-state electron configuration of oxygen, O, two  unpaired electrons are present. Explanation: To find out the number of unpaired electrons in oxygen, you need to write the electron configuration of O(Oxygen atom). Remember that the atomic number of oxygen is 8. Here is the ground state electron configuration of O: 1s²2s²2p⁴ =[He] 2s²2p ⁴ Remember that the p subshell has three orbitals.Each orbit can take maximum two electrons. In case of filling degenerate orbits ,each orbital will take one electron  before pairing by the second electron  according to Hunds' rule. Next

    In the ground-state electron configuration of iron, Fe, four  unpaired electrons are present. Explanation: To find out the number  of unpaired electrons in Fe, you need to write the electron configuration of Fe. Remember that the atomic number of iron is 26. Here is the ground state electron configuration of Fe: [Ar]3d⁶4s² Remember that the d subshell has five orbitals.Each orbit can take maximum two electrons. In case of filling degenerate orbits ,each orbital will take one electron  before pairing by the second electron  according to Hunds' rule. Next   In the ground-state electron configuration of Fe2+, four  unpaired electrons are present. Explanation: To find out the number of unpaired electrons in Fe^2+ ion, you need to write the electron configuration of Fe^2+. Remember that the atomic number of iron is 26. Here is the electron configuration of Fe^2+: [Ar]3d⁶ Remember that the d subshell has five orbitals.Each orbit can take maximum two...
