Which of the following statements about quantum numbers is wrong?a)If ...
Explanation:

The spin quantum number does not give the orientation of the electron cloud. The incorrect statement is option 'B'.

Quantum Numbers:

Quantum numbers are used to describe the properties and behavior of electrons in an atom. There are four types of quantum numbers: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (ml), and spin quantum number (ms).

Principal Quantum Number (n):

- The principal quantum number determines the energy level or shell in which the electron is located.
- It takes integer values starting from 1.
- The larger the value of n, the higher the energy level and the farther the electron is from the nucleus.

Azimuthal Quantum Number (l):

- The azimuthal quantum number determines the shape of the orbital.
- It takes integer values from 0 to (n-1).
- Each value of l corresponds to a specific shape of the orbital.
- For example, when l = 0, the orbital is s-shaped (s-orbital), when l = 1, the orbital is p-shaped (p-orbital), and so on.

Magnetic Quantum Number (ml):

- The magnetic quantum number determines the orientation of the orbital in space.
- It takes integer values from -l to +l, including zero.
- Each value of ml corresponds to a specific orientation of the orbital.

Spin Quantum Number (ms):

- The spin quantum number determines the spin of the electron.
- It can have two values: +1/2 (spin-up) or -1/2 (spin-down).
- The spin of an electron is not related to the orientation of its electron cloud.

The Zeeman Effect:

- The Zeeman effect refers to the splitting of spectral lines in the presence of a magnetic field.
- It can be explained by the magnetic quantum number (ml).
- The magnetic field causes the energy levels of the electrons to split, resulting in multiple lines in the spectrum.

Conclusion:

In summary, the incorrect statement is option 'B' because the spin quantum number does not give the orientation of the electron cloud. The correct statement is that the Zeeman effect is explained by the magnetic quantum number (option 'D').

Which of the following statements about quantum numbers is wrong?a)If ...
If the value of l=0, then electron lies in s-subshell which has spherical shape. So electron distribution is spherical.
Shape of orbital is given by azimuthal quantum number as it describes the subshell.
Magnetic quantum number determines the shift of atomic orbital due to external magnetic field i.e., zeeman effect.
Spin quantum number describes the spin of electron in particular orbital. Orientations of electron cloud is specified of a magnetic quantum number.
So B option is incorrect.
