Because the d-orbitals become split into two groups one having higher and other having lower energy so the transition of electrons within these groups continuously takes place which is also responsible for different colours of their compounds.

d-block elements are called transition elements because they exhibit multiple oxidation states and can form colored compounds due to the presence of partially filled d-orbitals. They also show variable valency and can easily form complexes with ligands, making them suitable for transitioning between different chemical behaviors. These elements occupy the d-block of the Periodic Table, hence the name transition elements.

D block elements are called outer transition elements because their outer or valence electrons are in transition.

Is carbon a representative element or transition?

Carbon is a representative element. It is located in group 14 of the periodic table, which is a group of representative elements also known as the "carbon group". Transition elements are typically found in the d-block of the periodic table.

Is nitrogen a transition or representative element?

Nitrogen is a representative element. Transitional elements are those found in the d-block of the periodic table, while representative elements are the s and p-block elements. Nitrogen is located in group 15 (formerly known as group V) of the periodic table.


Is barium a transition element or a representative element?

Barium is a representative element because it is an alkaline earth metal located in group 2 of the periodic table. Transition elements are typically located in the d-block of the periodic table.


What are the elements in groups 3 through 12 called on the periodic table of elements?

The elements in groups 3 through 12 on the periodic table are known as transition metals. These elements are characterized by their ability to form stable ions with partially filled d orbitals. They often exhibit multiple oxidation states and are known for their catalytic properties.
