The Transition Metals - also called the Transition Elements.

What are the Transition Metals?

The transition metals occupy the central block of the periodic table.
They are not a group (there is no group number) but they
are a collection of metals with common properties and many uses.
The transition metals are sometimes called a family of metals.

How many Electrons do the Transition Metals have?

The transition metals do not all have the same number of
electrons in their outer shell, and so they have different valencies,
forming 1⁺, 2⁺, or 3⁺ ions with non-metals.

Some of the transition metal elements may have
more than one valency and can have different oxidation states.
This is because of the properties of the fourth period
(4th electron shell) which can have a maximum of 18 electrons.
