w = what we want to know h = 6.63 x 10^-34 J s m = 9.1 x 10^-31 kg (mass of an electron?) v = I think that I calculete not im m/s

**chemistry**

now, we use the de Broglie equation to find the wavelength. Broglie equation: w = h / m v, where w = wavelength; h = Planck's constant in J/s; m = mass in kg; v = speed in m/s.

**chemistry**

the velocity of the electron is sqrt(2E/m) where E is the bond energy for NN and m is the mass of electron. So, v = sqrt (2 x 36.49 / 0.000548597 amu) v = 72.98/0.000548597 v= 133030.25
