Define transition elements and inner transition elements.
(N/A) Transition elements are those elements in which the $d$-orbitals are incompletely filled in their ground state or in any of their oxidation states. These are located in groups $3$ to $12$ of the periodic table.
Inner transition elements are those elements in which the $f$-orbitals are incompletely filled in their ground state or in any of their oxidation states. These are known as lanthanoids and actinoids,located in the $f$-block of the periodic table.
