Answer:

$\huge\mathfrak\pink{answer}$

Explanation:

1.S block-The S block in the periodic table of elements occupies the alkali metals and alkaline earth metals, also known as groups 1 and 2. Helium is also part of the S block. The principal quantum number “n” fills the s orbital. There is a maximum of two electrons that can occupy the s orbital.

2.P block-The P block contains groups 13, 14, 15, 16, 17, and 18, with the exception of Helium. (Helium is part of the S block.) The principal quantum number “n” fills the p orbital. There is a maximum of six electrons that can occupy the p orbital.

3.D block-The D block elements are found in groups 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 of the periodic table. The D block elements are also known as the transition metals. The d orbital is filled with the electronic shell “n-1.” There is a maximum of ten electrons that can occupy the d orbital.

4.F block-The F block elements are the lanthanides and actinides. The F orbitals of the electron shell are filled with “n-2.” There is a maximum of fourteen electrons that can occupy the f orbital.
