Question

(i) What are the quantum numbers and write their significance?

(ii) write the formula of de – Broglie’s wave equation?​

Answer 1

Answer:

Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atom's electrons. Quantum numbers are also used to understand other characteristics of atoms, such as ionization energy and the atomic radius.

Quantum means any physical entity that involves a reaction.

λ = h/mv, where λ is wavelength, h is Planck's constant, m is the mass of a particle, moving at a velocity v. ... Since then, the de Broglie equation has been shown to apply to elementary particles, neutral atoms, and molecules.

Answer:

(i) Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atom's electrons. Quantum numbers are also used to understand other characteristics of atoms, such as ionization energy and the atomic radius.

(ii) Apply the de Broglie wave equation λ=hmv λ = h m v to solve for the wavelength of the moving electron. ... This very small wavelength is about 1/20th of the diameter of a hydrogen atom.
