When iron is exposed to air in the presence of water, for example, the iron turns to rust—an iron oxide. When exposed to air, aluminum metal develops a continuous, coherent, transparent layer of aluminum oxide on its surface.

Oxidation state is a number assigned to an element in a compound according to some rules. This number enables us to describe oxidation-reduction reactions, and balancing redox chemical reactions.
The Group 2 metals react with water in a redox reaction to produce a metal hydroxide and hydrogen . The metal hydroxide forms as an alkaline solution , hence why the Group 2 metals are known as the alkaline earth metals. Example: Magnesium is oxidised from an oxidation state of 0 to +2. (Oxidation is loss of e - )
29 Αυγ 2023 · The oxidation state of an atom is equal to the total number of electrons which have been removed from an element (producing a positive oxidation state) or added to an element (producing a negative oxidation state) to reach its present state.
Oxidation state shows the total number of electrons which have been removed from an element (a positive oxidation state) or added to an element (a negative oxidation state) to get to its present state. Recognising this simple pattern is the single most important thing about the concept of oxidation states.
1 Αυγ 2020 · Oxidation is the loss of electrons or increase in oxidation state of a chemical species in a chemical reaction. Oxidation and reduction are two types of chemical reactions that go hand-in-hand to form redox reactions.
When a metal reacts with water, a metal hydroxide and hydrogen are formed. Metal + water → metal hydroxide + hydrogen. For example, sodium reacts rapidly with cold water, melting...
