Mg is a group 2A element, so it has a 2 oxidation number, and the hydrogens of H have zero ox. It's oxidation number increases, so Mg is oxidized in this reaction and we refer to HCl as an oxidizing agent or an oxidizer.numbers because that's hydrogen in its elemental form. Likewise, the oxidation number of H is reduced from 1 to zero, so hydrogen is reduced in this reaction and Mg is referred to as a reducing agent. Here are the assignments of the oxidation numbers; they're pretty straightforward: But this time when we compare oxidation numbers on the right and left, nothing has changed.Oxidation numbers are made-up or hypothetical numbers assigned to each atom in a reaction, individual or within a molecule.

Oxidation numbers refer to the ways in which an element shares electrons while part of a compound.
Positive oxidation numbers indicate that the element gives up electrons and acquires a local positive charge.

In another section we'll deal with reduction-oxidation ("redox") reactions, but in this section, we'll assign oxidation numbers to atoms and use them to determine whether or not the reaction is a redox reaction, and which atoms are oxidized and reduced in it.
The bromine atom in bromine fluoride, or Br F, has an oxidation number of 1.
In bromine dioxide, or Br O2, it has an oxidation number of 4.
This is because fluorine usually has an oxidation number of -1, and oxygen usually has an oxidation number of -2.

There are agreed-upon rules for assigning oxidation numbers.
I'll go through them here, but they're recapped in the table below.
