WebSep 27, 2024 · The atom is promoted to the 4s 1 3d 7 state in order to make bonds. A localized picture of the d-electrons for an individual iron atom might look like this: Since each unpaired electron has a spin moment of 1/2, the total spin angular momentum, S, for this atom is: S = 3 1 2 = 3 2 (in units of h/2π)

They can be magnetised and demagnetised. In the unmagnetised state the iron molecules point in all directions. When the iron is magnetised the molecules line up. Intensity of magnetism can be varied. When iron attains its maximum magnetism it is said to be saturated. lampara led media luna
