The elements in which electrons are progressively filled in 4f-orbital are called.
Y_Kistochka [10]

The elements in which electrons are progressively filled in 4f-orbital are called lanthanoids.

There are 15 metallic chemical elements called lanthanoids.

Those elements are with atomic numbers from 57 to 71.

Lanthanoids belong to f-block elements because of the filling of the 4f-orbitals.

One of the lanthanoids, lutetium (chemical symbol Lu) has 14 electrons if 4f orbitals.

Electron configuration of lutetium: [Xe] 4f14 5d1 6s2

f-orbitals are similar to the d orbital, but cut in half (eight lobes instead of four).

Lanthanoids are used not as materials in catalysts, alloys, lasers and cathode-ray tubes.
