Why is manganese not more ferromagnetic than iron, in spite of having more unpaired electrons? In pure paramagnetism, the dipoles do not interact with one another and are randomly oriented in the absence of an external field due to thermal agitation, resulting in zero net magnetic moment. In the classical description, this alignment can be understood to occur due to a torque being provided on the magnetic moments by an applied field, which tries to align the dipoles parallel to the applied field. any correct awnser get best vote.

Give the empirical formula of each of the following compounds if a sample contains the following quantities of each element.? , MS Chemistry & Organic Chemistry, University of Peshawar (2017) Answered 1 year ago Yeap it has 2 unpaired electrons but show a valance of 4 because it carry hybridization before bond formation which results in 4 unpaired electrons. Mn is element #25, so it has 25 protons and electrons. However in addition to the usual charge and magnetic interactions there is an interaction called the exchange interaction (I've linked to the Wikipedia article, but this is a complex area and hard going for the beginner). (a) Depict the electron configuration of this element using the noble gas notation and an orbital box diagram. The electrons fill the orbitals one by one. Laurence. Hund's Rule suggests that the 3d3 electrons go in separate orbitals before being forced to pair up, so a V atom has 3 unpaired electrons." Question.
