Answer the question below: Mary was performing experiments with atoms in her lab. She was measuring energy levels at various distances from an atom's nucleus. Would measurements taken closer to a nucleus result in lower energy levels? or greater energy levels or? Assuming that: As you go farther from the nucleus of an atom, the electron levels have more and more energy.
greater energy levels or
