Question

140. The azimuthal quantum number indicates
1) size of the orbital
2) shape of the orbital
3) orientation of the orbital
4) self spin of the orbital

Answer 1

Answer:

Options c is the right answer

Answer 2

Answer:

The shape of the orbital is given by

Ans The shape of the orbital is given by the azimuthal quantum number.

Note:

Principal, azimuthal, magnetic and spin quantum numbers are respectively related to size, shape, orientation and electron spin.

The principal quantum number gives the average distance of the electron from the nucleus. It corresponds to the principal energy level to which the electron belongs.

The azimuthal quantum number denotes the subshell (orbital) to which the electron belongs and also determines the shape of the orbital and the energy associated with the angular momentum of the electron.

The magnetic quantum number determines the preferred orientations of orbitals in space.

The spin quantum number 's' is related to electron spin. It was proposed by Uhlenbeck and Goldschmidt.
