Answer:

Principal Quantum Number- This quantum number designates the principal electron shell.

Angular Momentum Quantum Number-This quantum number determines the shape of an orbital and thus the angular distribution.

Magnetic Quantum Number- This quantum number determines the number of orbital number and their orientation within a subshell.

Step-by-step explanation:

Principal Quantum Number, n

This quantum number designates the principal electron shell. It denotes the energy and the most probable distance of the electron from the nucleus. Its value is always greater than or equal to 1, that is, n ≥ 1. It can takes values from n = 1,2,3,4.....The value n= 1 denotes the first principal shell, n = 2 denotes the second principal shell and so on.

Angular Momentum Quantum Number l

This quantum number determines the shape of an orbital and thus the angular distribution. It can take values from 0 to (n - 1). That is l = 0,1,2,...,(n - 1)

The magnetic Quantum Number, m

This quantum number determines the number of orbital number and their orientation within a subshell. The value of the magnetic quantum number varies from -l to +l. That is m = -l,(-l -1), (-l -2),..., 0, +(l -2), +(l -1), +l

Answer:

Principal Quantum Number: designates the principal electron shell. Angular Momentum Quantum Number-This quantum number determines it's shape of an orbital and thus it's angular distribution. This quantum number determines the number of orbital numbers, their orientation within the sub-shell.

Principal Quantum Number, n

It describes the size of its orbital and of the main energy level. It is represented by n. Where, n = 1,2,3,4....stands for K, L, M, N shell and so on..  

ngular Momentum Quantum Number l

It describes the shape of the orbital and thus the angular distribution. It can take  from 0 to (n - 1). That is l = 0,1,2,...,(n - 1)

The magnetic Quantum Number, m

It describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from . When l = 2, the value of  will be -2, -1, 0, +1, +2.
