The orbitals of the atom may be huge as it depends upon the shape of the atom,How big is it so the question here is whats the difference between orbit and the orbital well so lets discuss it.First of all the orbits are the definite path along the nucleus to where the electrons revolve and the orbital is defined as the space about the nucleus where the possibility of finding the electron is maximum so they both are different terms.Moving onto our topics what is the quantum number so it is the atomic parameter which describes the electron in all terms of their shape,size,and others hence it is described by the quantum numbers.A set
Of a four quantum number describes an atom completely and they are as follows
1. Principal quantum number: This is the first quantum number it describes the main energy level of the atom. It is denoted by the letter n. It can have only positive values ranging from 1 to infinity and the numbers designed to understand is 1,2,3,4 and also the alphabetical letters k,L,M,N in this way it says all about the main energy level of the shell .
2. Azimuthal quantum number: It is another type of the quantum number denoted by the letter l and it describes the shape of the sub shells in which the atoms are placed.It refers to the basic structure of the atom and gives us the information about the atom. It can have only positive integers ranging from 0 to (n-1).
3. Magnetic quantum number: It is the another type of the quantum number that determines the orientations of the atoms for the electrons in which the movement takes place. It is denoted by the symbol m and it has the integral values ranging from -l to +l through O. In this way it describes about the orientation make by the movement of the electrons.
4. Spin quantum number: It is the type of another quantum number. It is denoted by s and describes the spinning movement performed by the electrons about the atoms as we know that different rotations, spins and others are performed by the electrons and hence they are described as per the spin quantum number. It has only two values they are -half and + half.

Hence in this way the quantum numbers helps to define all the terms of the electrons of the atom by the help of this four quantum numbers.
