The inner transition metals are radioactive and are found in the f-block. These are commonly referred to as actinoids and are alkali metals.
Actually, it's the other way around. Electrons of transition metals fill d-sublevels, while electrons of inner transition metals fill f-sublevels. Inner transition metals are located in the f-block of the periodic table, while transition metals are located in the d-block.
Yes
Metals from the d-block (by opposition with the inner transition metals).
incomplete outer shells
Technetium has no stable isotopes.
Yes, transition metals are Group B elements found in the d-block of the periodic table. Inner transition metals, on the other hand, are located in the f-block of the periodic table and consist of the lanthanides and actinides.
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.
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.
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.
You think probable to artificial radioactive elements considered transition metals.
The most radioactive element in the transition metals group is technetium. It has no stable isotopes and is typically produced in nuclear reactors as a byproduct. Its most common radioactive isotope is technetium-99, which is used in various medical procedures such as imaging scans.
