Solution

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

Explanation:

The lanthanides which belong to the f-block elements are the elements where 4f-orbitals are filled progressively.

The electronic configuration of gadolinium (Atomic number 64) is ______.


In the modern periodic table, elements are arranged in order of increasing atomic numbers which is related to the electronic configuration. Depending upon the type of orbitals receiving the last electron, the elements in the periodic table have been divided into four blocks, viz, s, p, d and f. The modern periodic table consists of 7 periods and 18 groups. Each period begins with the filling of a new energy shell. In accordance with the Arfbau principle, the seven periods have 2, 8, 8, 18, 18, 32 and 32 elements respectively. The seventh period is still incomplete. To avoid the periodic table being too long, the two series of f-block elements, called lanthanoids and actinoids are placed at the bottom of the main body of the periodic table.
