1. The problem statement, all variables and given/known data Consider a neutral carbon atom that has six electrons orbiting the nucleus. Suppose that five of the electrons are in their lowest states,but the sixth is in a very high state. Why might the energy levels for the outermost electron be similar to those for the single electron in hydrogen. (Hint: Think of what is exerting an electrical force on the outermost electron.) 3. The attempt at a solution The 6 protons are attracting the outermost electron. Could the answer be something like the two attractive forces, between the outermost electron and 6 protons is equal to the single proton and electron in hydrogen?
