QUESTION 15
What do you expect the electrons in an atom to do if they are slowly hit by electrons with energy just under n=2?
The electrons would bump up to either n=2 or n=3.
The electrons would bump up to every possible energy level.
The electrons would not bump up.
The electrons would bump up to only n=2
The image represents the gaps between allowed energy levels for electrons. Which model best describes this phenomenon?
A. the wave model because electrons orbit the atom's nucleus in a continuous way
B. the particle model because electrons are particles
C. the wave model because the arrows show that the energy transfer is continuous
D. the particle model because the arrows represent discrete particle-like jumps
