Because the number of protons and electrons in the atoms of pure elements are equal so positive and negative charges are balanced.
Since manganese is a metallic element, its oxidation number in metallic form is 0, as for any other element.
For any element before reaction, its oxidation number is 0. Molecules made from the atoms of the same element have 0 oxidation state in each atom. Examples are gaseous hydrogen and liquid bromine.
Oxidation number of a free element is 0. Ex: Ag 2= 0
The element which has the same oxidation number in all of its known compounds is fluorine. Fluorine always has an oxidation number of -1 in its compounds because it is the most electronegative element.
Magnesium is in the group 2. 0 is the lowest oxidation number for it.
the oxidation number is 0

As a diatomic element, it would be neutral and = 0Refer to this site for other rules:http://www.brynmawr.edu/Acads/Chem/Chem103lc/GCoxidationnumber.htmlThe oxidation number of NO, nitrogen oxide, is +2.
The oxidation number of fluorine in the fluorine molecule (F2) is 0. In a molecule composed of the same element (like F2), each atom has an oxidation number of 0.
The oxidation number of S in S8 is 0. Each sulfur atom in S8 has an oxidation number of 0 because it is in its elemental form and not bonded to any other element.
Zero The oxidation number of an element in any of its elemental forms (allotropes) is always zero
In diamond, the oxidation number of a carbon atom is 0 because it is bonded to four other carbon atoms, resulting in a balanced charge. In graphite, the oxidation number of a carbon atom is also 0 for the same reason.
0 in elemental form +2 in its compounds
