An electron with a kinetic energy of 4.9eV collides inelastically with a stationary mercury atom. Why can you assume almost 100% of the electron's energy can go into raising the mercury atom to its first excited state?
I know that with an inelastic collision both energy and momentum are conserved but I'm just not sure how to word it or show that it is true.
M(electron)=5.49E-4 u
u = atomic mass unit
M(Hg)=201u
thank you in advance
