# Problem: What is the velocity of an electron that has a de Broglie wavelength approximately the length of a chemical bond? Assume the length of a chemical bond is 1.8×10−10 m . (The mass of an electron is 9.11 x 10-31 kg.)

We’re being asked to calculate the velocity of an electron that has a de Broglie wavelength approximately the length of a chemical bond? Assume the length of a chemical bond is 1.8×10−10 m.

Recall that the de Broglie wavelength (λ) can be calculated using:

$\overline{){\mathbf{\lambda }}{\mathbf{=}}\frac{\mathbf{h}}{\mathbf{mv}}}$

where:

h = Planck's constant (6.626 × 10–34 kg • m2/s)

m = mass (in kg)

v = velocity (in m/s)
