Homework Help: chemistry

Posted by anonymous on Wednesday, December 30, 2009 at 3:02pm.

The postulates of the Bohr model of the hydrogen atom can be stated as follows:

I. The electron can exist only in discrete states each with a definite energy.
II. The electron can exist only in circular orbits.
III. The angular momentum of the electron is nh/2pi where n is any positive integer.

a. State whether each of these postulates is currently considered to be correct, according to the wave mechanical description of the hydrogen atom.

b.Give the wave mechanical description that has replaced one of the postulates now considered to be incorrect.

---

I read (or at least tried to read) through the wave mechanical description in my textbook, but the only thing I got out of it is that II is correct. My hunch is that III is incorrect, but I don't know for sure. Help please?

Thank you!
