Homework Statement
a) Consider a hydrogenic atom consisting of a carbon-12
nucleus and a single electron. What is the wavelength of the
photon emitted when this atom drops from n = 5 to the n = 2
state?
b) According to the Bohr theory, what is the distance
between the electron and the nucleus in the n = 2 state of the
hydrogenic carbon-12 atom?
Homework Equations
[itex]r_n = n^2 \times a_0[/itex]
where [itex]a_0[/itex] is the bohr radius
The Attempt at a Solution
I found the answer to part A no problem, but b is giving me trouble.
I know that the equation for the radius for excited states is for a hydrogen atom. WIth a carbon nucleus I expect it to be much smaller that the bohr radius, but I can't figure out how to account for the change in nucleus size.
Any ideas?
