Question

When an atoms oxidation number increases what else happens?

it is the same as the atoma_____ electrons we say that it is _____ it would be in a molecule called a_____ this change would happen at the _____

Answer 1

An increase in an atom's oxidation number signifies a loss of electrons, indicating oxidation. This is often observed in redox reactions where there is a transfer of electrons, and the atom undergoing an increase in oxidation number becomes oxidized.

Step-by-step explanation:

When an atom's oxidation number increases, it means the atom loses electrons and is said to be oxidized. This is common in redox reactions, where a transfer of electrons occurs between reacting species. An increase in oxidation number often signifies that an atom has formed a bond with a more electronegative atom, indicating a shift in electron density. A classic example of oxidation is when a carbon atom's oxidation number increases, while another atom, like iron, in the same reaction sees a decrease in oxidation number — representing reduction. It's essential in balanced redox equations that the number of electrons lost equals the number of electrons gained.

In terms of molecular language, the atom that loses electrons and becomes oxidized may form part of a compound referred to as an oxidizing agent. The change in oxidation number, and hence the loss or gain of electrons, occurs at the reaction site. Oxidation numbers are a useful tool for chemists to track these electron transfers during chemical reactions.
