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!!!
