An electron of kinetic energy 10 eV collides with a hydrogen atom in the 1st excited state. Assuming the loss of kinetic energy in the collision to be quantized, the collision:
Options:(select one or more)
Answer:
A, B, C
Solution:
The atom is in ; the 10 eV electron can lose any quantized amount (excitation to or ionisation, needing only 3.4 eV) or none at all. So the collision may be elastic, inelastic, or perfectly inelastic - never "must be" inelastic.
