The elements in which 4f orbitals are progressively field up are called as

A

Transition elements

B

Lanthanides

C

Actinides

D

Inert gases

Text Solution

Verified by Experts

The correct Answer is:
B

The elements in which electrons are progressively filled in 4f – orbital are called lanthanides. Lanthanides consist of elements from `Z = 58` (cerium) to 71 (lutetium).
