Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.

As element 34, it has 34 electrons. 2+8+18 is 28. Therefore, six electrons are on its valence shell. It all depends on shells accepting an amount of electrons.

The electron configuration for magnesium is \begin{align*}1s^22s^22p^63s^2\end{align*}. The outer energy level for this atom is n = 3, and it has two electrons in this energy level. Therefore, magnesium has two valence electrons.

KMnO4 is a strong oxidising agent because the main metal atom (Mn) is in a very high +7 oxidation state, which means it's lost all its valence electrons. Although manganese can lose 7 electrons, it would prefer to have some, so it will readily grab them from somewhere else and in doing so oxidise the other species.

Manganese, in particular, has paramagnetic and diamagnetic orientations depending on what its oxidation state is. Mn 2O 3 is manganese(III) oxide with manganese in the +3 state. 4 unpaired electrons means this complex is paramagnetic.

There are 2 oxygens and each has a 2- charge, so the anion is 4-. The overall compound is uncharged, which means the one Mn must be in the 4+ oxidation state. ... So the correct name is “manganese (IV) oxide”. But chemist often call it manganese dioxide.

So... for the element of MAGNESIUM, you already know that the atomic number tells you the number of electrons. That means there are 12 electrons in a magnesium atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and two more in shell three.
