(n-1)d 1–10 ns 1–2
Which of the following is an example of an inner transition metal?
Thorium (Th)
Why are precious metals like silver, gold, and platinum considered part of the transition metals series?
Due to their electronic configurations
What distinguishes transition elements from non-transition elements based on their electronic configuration?
Partially filled d or f orbitals

Why are zinc, cadmium, and mercury not regarded as transition metals?
They have a full d 10 configuration in their ground state and common oxidation states.
What is the key difference between transition metals and inner transition metals?
Transition metals have incomplete d subshell, while inner transition metals do not.
Why were transition metals originally named 'transition metals'?
Due to their position between s and p-block elements in the periodic table.
