question 3 what may happen to the electron when it gains energy? it may move to a higher energy level. it may drop to a lower energy level. it will never change location. question 4 which model is bohr credited with developing? the nuclear model of the atom the orbital model of the atom the plum pudding model of the atom the periodic table

Explanation:

For Question 3, in atomic theory, when an electron gains energy, it moves to a higher - energy level. For Question 4, Niels Bohr is credited with developing the orbital model of the atom which describes electrons moving in fixed orbits around the nucleus.

Answer:
