Given the question: Greg was studying Bohr's model. He found it helpful to categorize different scenarios in the model. First, he labeled electron with higher energy as cat A, and electron with lower energy as cat B. Then he labeled electron that gained energy as cat C, and election that lost energy as cat D. Given the paragraph above, please answer correctly the following question: Which energy level would cat B reside, higher energy level or lower energy level?
The answer is:
lower energy level
