Question

Explain the significance of quantum number.

Answer 1

Step 1: Explanation for quantum number.

1. Quantum numbers are a collection of numbers that helps in describing the position as well as the energy of an electron.
2. There are 4 types of quantum numbers, that is, principal, azimuthal, magnetic, and spin quantum numbers.
3. An orbital is identified by 4 quantum numbers.
4. 4 quantum numbers are used to fully describe all of the attributes of a given electron.

Step 2: Significance of quantum numbers.

1. Principal quantum number: The size and energy of the orbit are defined by this quantum number.
2. Azimuthal quantum number: The shape of the orbitals is defined by this quantum number.
3. Magnetic quantum number: The spatial orientation of the orbital is determined by this quantum number.
4. Spin quantum number: The spin of the electron is indicated by this quantum number.
