A doubly ionized lithium atom has an electron in the n = 4 state. What is the electric potential energy of the electron?
The Bohr model can be applied to singly ionized helium
He+ (Z = 2). Using this model, consider the
series of lines that is produced when the electron makes a
transition from higher energy levels into the = 4 level. Some of
the lines in this series lie in the visible region of the spectrum
(380−750 nm). What are the values of for the energy levels
from which the electron makes the transitions corresponding to
these lines?
