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.
No, pb is the chemical symbol for lead, which is not classified as an inner transition metal. Inner transition metals are elements located in the f-block of the periodic table, such as the lanthanides and actinides. Lead is classified as a post-transition metal.
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.
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.

Actinium is the first member of the actinoids family.Actinium is a solid, inner transition metal, radioactive, very rare.
Nickel is not an inner transition element.
Yes, actinium is an inner transition metal.
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.
A chemical element, one of the inner transition elements.
When an electron moves from an outer to an inner orbit, energy is released in the form of light of a particular wavelength.

This chemical element is erbium.
Technetium (atomic number 43) is the inner transition metal with the lowest atomic number.
The element with atomic number of 91 is protactinium, Pa. It is an inner transition metal.
The most unstable species in the periodic table among transition and inner transition elements is #43 Technetium (Tc). It is so unstable that it does not occur naturally.
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.
