How can chlorine have an oxidation number of 3 in chlorite ? Chlorine has to have an oxidation state of +3.
The iron ion Fe 3 + , for example, has an oxidation number of +3 because it can acquire three electrons to form a chemical bond, while the oxygen ion O 2 − has an oxidation number of −2 because it can donate two electrons.
Cl has a -1 oxidation number, except when bonded to a F or an O.
The oxidation number of a free element is always 0. The oxidation number of a monatomic ion equals the charge of the ion . The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements. The oxidation number of O in compounds is usually -2, but it is -1 in peroxides.
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen . Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.

Oxidation number means that the number of electrons either lost or gained by an atom of an element during compound formation. The oxidation number of chlorine are +1,+3,+5,+7 and -1. However for Chlorine gas, the oxidation number (Cl2) is zero .
compounds, the chlorine element is in its highest oxidation state of +7 .
So, two chromium atoms have an oxidation number of +12. So one chromium atom will have an oxidation number of +12 /2=+6. So oxidation number of Cr in K 2 Cr 2 O 7 is +6 .
N2 is a molecule that is the elemental form of nitrogen, and its atoms have no charge. The oxidation number for these S, K, and N atoms will be zero .
Answer: The oxidation number of nitrogen is +2 .
Oxidation is defined as a process in which an electron is removed from a molecule during a chemical reaction . ... In other words, during oxidation, there is a loss of electrons. There is an opposite process of oxidation known as a reduction in which there is a gain of electrons.
Oxidation is the process when oxygen combines with an element, changing the appearance of the element. When iron reacts with oxygen and changes to rust , this is an example of oxidation. When fire burns up a wooden log, this is an example of oxidation.
Both Tc and Re are reduced more readily in the lacunary α1 site as compared to the α2 site. The DFT calculations elucidate that the highest oxidation state attainable for Re is VII while, under the same electrochemistry conditions, the highest oxidation state for Tc is VI .
Magnesium is in group 2 so it will have an oxidation state of +2 .
