question 2b i

Why is it that if an electron has insufficiect KE to excite an orbital electron, it will not transfer energy? Wouldn't it still transfer the energy it does have?


Confused...

This is one of the “confusing” features in Quantum theory or Physics.

One of the necessary conditions for transfer of energy in the “inelastic” collision between the incoming electron and orbital electron is that the amount energy transfer must be equal to the energy difference between two energy levels (original level and excited level).

If you look at the energy diagram above, the orbital electron in the ground purple energy level can be excited to the blue or red energy level but not in between, because the energy level is "quantized".

One more thing if you have answered 2(a) or understand 2(a) answers, it should not be too difficult to understand the answer for 2(b)(i).

It will transfer that energy, but it will not excite the electron. The electron will just wobble around a bit to get rid of the excess energy
