Transition elements are elements that have two or more states that they can exist in. The most common transition element is the element
A div can exist as a block-level element or an inline element.
Properties of Transition Elements
A transition element is a chemical element that lies in the d-block of the periodic table, between the groups 3 and 4, and elements 21 and 22. The transition elements are so named because they are typically good at moving electrons from one atom to another. This ability to easily donate or accept electrons makes them important in creating chemical bonds.
Some of the most important properties of transition elements include their ability to form colored compounds, their high melting and boiling points, and their ability to resist corrosion. Many transition elements are also used in various industrial applications, including in the production of alloys, magnets, and medicines.
Oxidation States
In chemistry, an oxidation state is a measure of the degree of oxidation of an atom in a chemical compound. The oxidation state of an atom is a positive integer. The sum of the oxidation states of all atoms in a molecule must be zero.
The oxidation state of an atom is determined by its electron configuration and by the number of electrons that it loses, gains, or shares in order to form a chemical bond.
The most common oxidation states of atoms in organic molecules are −2, −1, 0, +1, and +2. However, oxidation states can also be negative.
