Question

5f elements are called ​

Answer 1

Answer:

The electron obtained on successive filling of 5f orbitals are called actinides or actinides. They are so called because they come immediately after actinium (Ac) in periodic table. Fourteen elements from Th(90) to Lw(103) comprise actinide series, and are also called second inner transition series.
