What is the energy of a collection of 3 electrons arranged in an equilateral triangle with sides 1 ˚A (1 ˚A = 10-10 m)? (1 ˚A is approximately the diameter of an atom, which makes this calculation an approximation of the energy of the electron configuration in Lithium (not including the nucleus, which has a large effect).)

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...
