Chemistry Question on Structure of atom

Who proposed dual nature of electron?

A

de-Broglie

B

Einstein

C

Bohr

D

Heisenberg

Answer

de-Broglie

Explanation

Solution

Dual nature of electron was first proposed by de-Broglie. He gave the following equation for the wavelength of electron. λ=hmv\lambda =\frac{h}{mv} He proposed that all mieroparticles like electrons, protons, neutrons etc. have dual nature i.e., both wave nature as well as particle nature. Interference and diffraction support the wave nature of electron. E=mc2E=mc^{2} support the particle nature of electron. E=hv=hcλE=hv=\frac{hc}{\lambda } is de-Broglie equation, it supports both wave nature and particle nature of electron.
