electron carries negetive charge and he round the around nucleas

Answer 2

Answer:

λ= $\frac{h}{mc}$ = 6.63 x $10^{-34}$/(9.1 x $10^{-31}$ x 3 x $10^{8}$ ) =2.4285 x $10^{-58}$

Explanation:

de Broglie proposed that a particle such as an electron could be described by a wave whose wavelength is given by

where

h  is Planck’s constant,

m  is the mass of the particle, and

v  is the velocity of the particle.
