So I have two teachers, and both teachers keep telling me two different things and I don't know who to believe.
1st Teacher: Says that when an electron gets more than enough energy to shift to the first energy level, but not enough to shift to the second, the electron shifts to the first and the remaining energy becomes Kinetic Energy(so the electron orbits faster).
2nd Teacher: The electron has to gain exactly the amount of energy needed to shift to an energy level or else it doesn't shift at all.(Even when the electron has more than enough energy to shift to the first energy level but not the second)
So which theory is right?
