Question

1. look at the model. then, answer the question and choose the best answer. what would have to happen for an electron to go from a lower energy level to a higher energy level? the nucleus would have to lose energy. the electron would have to lose energy. the electron would have to gain energy. the nucleus would have to gain energy.

Explanation:

In an atom, for an electron to transition from a lower - energy level to a higher - energy level, it must absorb energy. This is because higher energy levels are associated with greater amounts of energy. The nucleus is not directly involved in the electron's energy gain for this type of transition. Losing energy would cause the electron to move to a lower energy level instead.

Answer:

The electron would have to gain energy.
