1. The problem statement, all variables and given/known data
hi
this is a problem that puzzles me. it goes like this:
energy/10?18 J
ionisation level 0.0
level D
level C
level B
ground state A
?1.9
?2.1
?2.4
? 4.6

An electron with kinetic energy 2.6 × 10?18 J collides inelastically with an electron
in the ground state.
State which energy levels may be occupied following this collision.

A photon of energy 2.6 × 10?18 J is incident on an electron in the ground state.
State and explain what would happen.



2. Relevant equations
e= h1 - h2



3. The attempt at a solution

i looked at the kinetic energy needed to escape the ground state. if i calculate 4.6-2.6, i get 2j of kinetic energy. the electron cant get to level d. will b to c be correct?

for the second part, i am speculating the kinteic energy will have no effect at the ground level. but i am not totally sure. can someone please explain.

please comment.

Im sorry no one will help you unless you help us, its really annoying when people ask for help but set everything out poorly
