Transition Elements are the element in the d-block, which includes groups 3 to 12 on the periodic table.
Transition metals are the ones that have valence electrons i.e., electrons that can participate in the formation of chemical bonds in two shells instead of only one. Transition metals are good examples of advanced shell and orbital ideas. They have a lot of electrons and share them in different ways. Most transition metals are shiny.
Some examples of Transition Metals are:
The f-block lanthanide and actinide series are also held as transition metals and are called ‘inner transition metals’.
