Answer to Question #266758 in General Chemistry for MCC

Question

Determine the magnetic property of manganese by showing the electron configuration and valence orbitals

Answer 1

Electronic Configuration of Manganese

$[AR]3d^5\>4s^2$

Valency orbitals

$\downarrow\uparrow\>\>\>\>\downarrow\uparrow\>\>\>\uparrow\>\>\>\downarrow\uparrow$

$-$ $-$ $-$ $-$

3d. 4s

It has unpaired electrons in 3 d, therefore it is paramagnetic though weak by itself it is not magnet, but when combined with Aluminium, Copper, Antinomy. The result in alloy, it's highly ferromagnetic
