calculate the speed of an electron if its de broglie wavelength is twice its displacement in one second
valkas [14]

Answer:

The speed of an electron is 0.01908 m/s.

Explanation:

De-Broglie wavelength is given by:

\lambda=\frac{h}{mv}

where,  \lambda = wavelength of a particle

h = Planck's constant = 6.626\times 10^{-34}Js

m = mass of particle

v = velocity of the particle

Velocity of an electron = v

Mass of an electron = 9.1\times 10^{-31}kg

Wavelength of electron is twice the displacement in seconds which is velocity of an electron.

Then.wavelength of an electron = \lambda =2v

\lambda =2v=\frac{6.626\times 10^{-34}Js}{9.1\times 10^{-31}kg\times v}

v = 0.01908 m/s

The speed of an electron is 0.01908 m/s.

Ions are atoms that have gained or lost which subatomic particles?
Bad White [126]
Protons cannot be lost without the atoms becoming an entirely different element. Elements can infact have different numbers of neutrons within the same element, but neutrons are not related to the electrical charge. The answer is c. electrons.
