Question

The three dimensional region in space around nucleus, where there is the existence of probability spots of electrons is called :

• A. orbit
• B. orbital
• C. probable space
• D. both $B$ and $C$

Answer 1

The correct option is D both $B$ and $C$

Orbit	Orbital
It is well-defined circular path followed by electron around nucleus.	It is a region of space around the nucleus where the probability of finding an electron is maximum.
It represents two dimensional motion of electron around nucleus.	It represents three dimensional motion of electron around nucleus.
The maximum no. of electrons in an orbit is $2n^2$.	The maximum no. of electrons in an orbital is 2.
Orbit is circular in shape.	Orbitals have different shapes.
