◆There are 4 blocks in periodic table ...

◆ s-block elements = The elements in which the last electron enters the s-orbital of their outermost energy level are called as block elements.

◆ p-block elements = The elements in which the last electron enters the P orbital of their outermost energy level are called p-block elements.

◆ d-block elements = The elements in which the last electron enters the d orbitals of their the last but one called penultimate energy level constitute d-block elements.

◆ f-block elements = The elements in which the last electron enters the f orbitals of their atoms are called f-block elements.

Hope it helps you✌✌✌
