Explanation / Answer

Four quantum numbers

Symbol used for the quantum number = 'n'

Name the quantum number = Principal quantum number

Allowed values of the quantum number= n can be 1,2,3,4,.... etc , i.e. any integer

Impact of the quantum number on atomic structure /properties :-

1.It is used to explain the main lines of spectrum

1.It tells the main shell in which the electron resides.

2.It gives the approximate distance of elctron from the nucleus.

3.It is used to explain the main lines of spectrum

Symbol used for the quantum number = 'l'

Name the quantum number = Azimuthual quantum number

Allowed values of the quantum number = For a particular value of 'n', l =0 to n-1

Impact of the quantum number on atomic structure /properties :-

1. It tells the number of subshells present in any main shell.

2. It tells about the relative energies of the subshells.

3. Shapes of orbitals.

4. It is used to explain the fine structure of line spectrum.

Symbol used for the quantum number = 'm'

Name the quantum number = Magnetic quantum number

Allowed values of the quantum number= For a particular value of 'l' , m = -l to + l, including zero

Impact of the quantum number on atomic structure /properties :-

1. It tells about the number of orbitals present in any subshell or the number of orientations of each subshell.

2. It is used to explain the splitting of lines in a magnetic field.

Symbol used for the quantum number = 's'

Name the quantum number = Spin quantum number

Allowed values of the quantum number= for any particular value of 'm', s can be +1/2 or -1/2

Impact of the quantum number on atomic structure /properties :-

1. It tells the direction of electron spin, i.e. clockwise or anticlockwise

2. It is used to explain the magnetic properties of substances.
