(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In a classical model of the hydrogen atom, the electron moves around the proton in a circular orbit of radius 0.053 nm.

What is the electron's orbital frequency?

What is the effective current of the electron?

2. Relevant equations

Freq * Wavelength = Speed of light

(V*lambda = c)

Lambda = (plancks constant)/momentum

momentum = (mass of electron)*(Velocity)

F = qE = m(v^2)/R

current....I = q*ie....(charge of electron)*(electron current)

number of electrons...Ne = ie*delta_t....(electron current)*(period I presume)

Ne = 1

3. The attempt at a solution

Mass of electron = 9.1094*10^-31 kg

qe- = -1.6*10^-19 coulombs

radius = 0.053*10^-9 m

...utlizing this information I found the velocity from the Force equation, deriving:

sqrt(K(q^2)/(r*me-) = v

Then plugged in velocity into the equation: lambda = h/(mv)

Plugged lambda into: V = c/lambda

....finding my frequency to be about 900*10^15 Hz....but this was wrong. Help would be extremely appreciated!!!
