Quizplus · Accepted Answer

When an atom's electrons are in their ground state, they are in the lowest energy level and therefore do not emit visible light. This is because visible light corresponds to specific energy level transitions, which do not occur when the electrons are in the ground state. If most of the electrons in the air's atoms were excited to metastable states or relatively cool, visible light emission could occur. However, this is not the case, so option B and C are ruled out. Option D is true, but it is not directly related to the absence of visible light emission. Option E is also not directly related, as electron spacing does not impact visible light emission.
