Excitation and deexcitation: Day 1, P1
Atoms Can be Excited
page 2 of 6
Atoms interact by attracting each other, but when they get too close they bounce off and go their separate ways. It turns out that's not the only thing that can happen. Through your observations and experimentation determine what else is going on in these models?

The total energy is conserved.
The atoms appear to behave like balls in the pendulum in the picture.
The atoms exchange energy.
When the green atom is moving the pink atom does not move.
When the pink atom is moving the green atom does not move.
