Is the The oxidation number of an atom is shown with a subscript?
No, the oxidation number of an atom is typically written as a superscript, not a subscript. It is denoted next to the symbol of the atom to represent the charge that the atom carries in a compound or ion.
When oxidation number positive or negative?
In general, oxidation numbers are positive when an atom loses electrons (oxidation) and negative when an atom gains electrons (reduction). The oxidation number reflects the charge that the atom would have if the electron was completely transferred.
What is meant by oxidation number of an atom?
The oxidation number of an atom describes the number of electrons that an element has partially/entirely accepted/donated. A neutral atom has oxidation number of 0. When forming an ion, the overall oxidation number is equivalent to its charge.
What is an atoms oxidation number?
The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.
What is the oxidation number of any atom in the element state?
The oxidation number of an atom in its elemental state is 0. This is because the atom has an equal number of protons (positive charge) and electrons (negative charge), resulting in a neutral overall charge.

What is an atom's oxidation number?
The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.
What is an oxidation number and how does an atom get one?
Before involving any chemical reactions or bonds, an atom has an oxidation number of zero. Accepting electrons will lower the oxidation number to negative numbers. Discharging electrons such as metals will result in positive oxidation numbers.

When an atom in a reactant gains electrons what happens to its oxidation number?
The oxidation number decreases because gaining electrons leads to a more negative charge, reducing the overall positive charge of the atom.
Does an element that loses electrons when bonding with other atoms have a negative oxidation number?
No. The lower (or 'more negative') the oxidation number, the more electrons the atom has. This is because the oxidation number is a measure of the charge on that molecule and, since electrons have negative charge, more of them give a more negative oxidation number. So if an atom loses electrons during bonding, it has lost some of its negative charge - giving it a more positive oxidation number.
How does the oxidation number indicate if an electron will be lost or gained?
The increase in oxidation number indicates loss of electrons, while a decrease indicates gain of electrons. For example, if an atom's oxidation number increases from +2 to +4 in a reaction, it has lost two electrons. Conversely, if the oxidation number decreases from +4 to +2, it has gained two electrons.
What is a oxidation number of an atom?
For example the atomic number of oxygen is 8.
