guarantee its correct :)
The change in electrons for manganese in the following reaction 2 MnO 4 - ( aq ) + H 2 O 2 ( aq ) + 6 H + ( aq ) -> 2 Mn 2+ ( aq ) + 3 O 2 ( g ) + 4 H 2 O( l ) is that mangnese is loosing 2 electrons and attend the oxidation sate or oxidation number of +2.
what is the oxidation state or oxidation number?
The oxidation number of an atom in a molecule is the charge that the atom would have adapt after loosing or sharing of electrons, it specifies many things about the stability of the of the atom as it simplifies that the orbital is full filled or half filled.
The oxidation number of an atom in a neutral free element or stable element is zero.
Oxidation number also named oxidation state, total number of electrons that an atom either gains or accepts or loses niether donates to form a chemical bond with another atom.
Therefore, manganese is losing 2 electrons.
