Homework Statement
hi
this is a problem that puzzles me. it goes like this:
energy/1018 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 × 1018 J collides inelastically with an electron
in the ground state.
State which energy levels may be occupied following this collision.
Homework Equations
e= h1 - h2
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 can't get to level d. will b to c be correct?
please comment.
