Which quantum number determines energy of electron and orientation of orbital?
Answers
Magnetic quantum number determines about orientations and orbitals in which electron is present.
Answer: Magnetic quantum number
Explanation:
The magnetic quantum number of an electron is one of the four quantum numbers that state the position of the electron with respect to the nucleus.
The magnetic quantum number is the third on the list between spin and azimuthal quantum number. It splits the sub-shells ( such as s,p,d,f) into individual orbitals and places the electron in one of them. It defines the orientation in space of a given orbital of a particular energy (n) and shape (I).
In each sub-shell, the number of orbitals is given as 2+1, where is the azimuthal quantum number. By that process, we can find out the orbital in every sub-shell.
Since magnetic quantum number is dependent on azimuthal quantum number, its value ranges from – to +, including 0.
For example, s sub-shell has only one orbital, the p sub-shell has 3 and d has 5 and so on.
