E) 7

Question

Quizplus · Accepted Answer

An atom with four accessible energy levels can emit a maximum of six different wavelengths. This is because an electron can transition from any of the four higher energy levels to any of the three lower energy levels, resulting in six possible transitions and six different wavelengths of light emitted.
