Question

explain the classification ofs, p, d &f orbital ​

Answer 1

Answer:

s-Block Elements -

Elements in which the last electron enters the s-orbital of the outermost energy level are called s-block elements.

The s-block consists of two groups—Group 1 and Group 2, which are alkali metals and alkaline earth metals.

p-Block Elements -

Elements in which the last electron enters the p-orbital of their outermost energy level are called p-block elements.

The p-block elements comprise elements belonging to Groups 13−18.

It consists of all types of elements—metals, non-metals and metalloids.

d-Block Elements (Transition Elements)

Elements in which the last electron enters any one of the five d-orbitals of penultimate shells are called d-block elements.

Elements of Groups 3−12 in the center of the periodic table constitute the d-block elements.

The general outer electronic configuration of d-block elements is (n − 1)d1−10 ns1−2.

f-Block Elements (Inner Transition Elements)

Elements in which the last electron enters any one of the seven f-orbitals of their respective ante-penultimate shells are called f-block
