A singly ionized helium atom is in the ground state. It absorbs energy and makes a transition to the n = 3 excited state. The ion returns to the ground state by emitting several photons. What is the wavelength of the highest energy photon?
A singly ionized helium atom is in the ground state. It absorbs energy and makes a transition to the n = 6 excited state. The ion returns to the ground state by emitting FIVE photons ONLY. What is the wavelength of the second-highest energy photon?
A singly ionized helium atom is in the ground state. It absorbs energy and makes a transition to the n = 5 excited state. The ion returns to the ground state by emitting FOUR photons ONLY. What is the wavelength of the second highest energy photon?

8. A singly ionized helium atom is in the ground state. It absorbs energy and makes a transition to the n = 7 excited state. The ion returns to the ground state by emitting SIX photons ONLY. What is the wavelength of the second highest energy photon?
A singly ionized helium atom has only one electron bound to the nucleus. What is the radius of the ion when it is in the second excited state? r = 1.03 x 10-10m r = 1.52 x 10-10m r = 2.15 x 10-10m r = 2.38 x 10-10m
A doubly ionized lithium atom has an electron in the n = 4 state. What is the electric potential energy of the electron?
Problem 2: Helium Spectra In helium, there are two electrons, which makes the math in finding their energy levels much more complicated. As a first approximation to that math, we can use Bohr energy levels with Z = 1.34 for the neutral helium atom (ie when both electrons are present), and Z = 2 for the singly ionized helium atom (ie when only one electron is present). The lower Z value for the neutral helium atom can be thought of...
Part A What is the change in energy ?E of the hydrogen atom as the electron makes the transition from the n=3 energy level to the n=1 energy level? Express your answer numerically in electron volts. Part B When an atom makes a transition from a higher energy level to a lower one, a photon is released. What is the wavelength of the photon that is emitted from the atom during the transition from n=3 to n=1? Express your answer...
