Give names of four classes into which the elements have been classified and mention to which groups of the modern period table they belong

Dear student,

 four types of elements of the periodic table based on electronic configurations are :

 

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.

 

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.

 

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.

 

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.
