The size of atoms varies by only a factor of three or so,from largest to smallest, yet the number of electrons variesfrom one to over 100. Explain
. A general expression for the energy levels of one-electron
atoms and ions is
uk q°q²
E,
2h'n?
Here u is the reduced mass of the atom, given by u = m, m,/
(m, + m2), where m is the mass of the electron and m, is the
mass of the nucleus; k, is the Coulomb constant; and q and
2 are the charges of the electron and the nucleus, respec-
tively. The wavelength for the n= 3 to n = 2 transition of the
hydrogen atom is 656.3 nm (visible red light). What are the
wavelengths for this same transition in (a) positronium, which
consists of an electron and a positron, and (b) singly ionized
helium? Note: A positron is a positively charged electron.
The structure of an atom is analogous to a model of the solar system. Explain why this statement is true.
