The final electron in inner transition metals typically enters the 4f or 5f orbitals. These orbitals are part of the inner electron shells and are responsible for the unique chemical properties of inner transition metals.
When an electron moves from an outer to an inner orbit, energy is released in the form of light of a particular wavelength.
No, electrons of inner transition metals fill f-sublevels, while electrons of transition metals fill d-sublevels. Inner transition metals have their f-sublevels as part of their electron configuration, whereas transition metals have d-sublevels as part of their electron configuration.
Lanthanides are called inner transition elements because they fill the 4f orbitals, which are part of the inner electron shell transition metals. These elements are also characterized by the gradual filling of the 4f subshell across the lanthanide series.

F-block elements are called inner transition elements because they have partially filled f orbitals, which are part of the inner electron shell. These elements typically have electrons filling the f orbitals after the d orbitals, hence the term "inner transition."
Electromagnetic radiation
Energy lost by an electron during its transition from an outer to an inner orbit is emitted as a flash of light called an emission. Light/energy emissions are released in a characteristic manner (wavelength) that corresponds to the amount of energy lost.
Under normal conditions, all of the inner shells are already full to their maximum occupancy, and so no additional electrons can go into the inner shell. Only with excitation with light can you create a vacancy in the inner shell such that outer shell electrons can fill that vacancy. This requires excitation with either ultraviolet light or x-rays.
Nickel is not an inner transition element.
The lanthanides and actinides are known as the inner transition metals. They are located at the bottom of the periodic table and have electron configurations that include f-orbitals. They share similar chemical properties due to the filling of their f-orbitals.
