A chemical element known as a transition metal (or transition element) has a partially full d subshell whether it is present as an element or as an ion in compounds, allowing the d orbitals to participate in chemical bonding. A standard used to categorise them is that the transition metals are roughly those elements in the periodic table's d-block. Although there are many different definitions of the word "transition metal," it often refers to all elements in groups 4 through 11, as well as scandium and yttrium in group 3. They frequently also include lutetium and lawrencium, or lanthanum and actinium. Inner transition metals, sometimes referred to as transition metals, are the lanthanide and actinide series from the f-block. They are glossy and exhibit good thermal and electrical conductivity.
