Referring to the ground state orbital diagram of Fe and Fe3+, explain why iron is considered a ferromagnetic element.
1 answer:
Iron having Z=26 with electronic configuration as has 6 electrons in the 3d shell wherein 5 electrons are aligned parallely and 1 electron as antiparallel.
having electronic configuration as
has 5 electrons, all aligned in the same direction.
Iron, when kept in external magnetic field, the magnetic domains of the atom get aligned in one direction that means it becomes parallel and they remain parallel even after removing the magnetic field therefore, it is considered as ferromagnetic.

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>
Sublimation is a process in which the solid molecules gain energy from their surrounding and they now have enough energy to overcome the force of attraction with the neighboring molecules, thus they escape into the surrounding without going through the liquid phase, that means they directly jump to the vapor phase.
<h2>_____________________________________</h2><h2>Endothermic</h2>Those process which absorb energy from their surrounding to form the product are called endothermic process. Since the SUBLIMATION requires additional energy, it is an endothermic change.
