Bohr atom and velocity
« on: April 28, 2006, 09:15:29 AM »
Hello all,
I'm doing some general problems and got stuck in this one:

How do you calculate the velocity of the electron in the first Bohr orbit of the hydrogen atom, and then for the He+ ion?
Help?
Thanks in advance!

I think you should use the formula:

v = Ze2/2nhe0

Borh radius is clasically a0 = (4*pi* e0)(h / (2 pi * m Z e2)

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
