Do molecules gain or lose protons as the atomic number goes higher?
Gain.
The molecules move freely past on another but are close together.
What is the kinetic molecular theory?
The theory that all matter consists of constantly moving particles.

Gas.
Do elements gain or lose electrons in a bond?
Lose in columns 1 and 2 and gain in the other columns.
The don’t move past on another and vibrate in place.
How is the kinetic theory of matter different from the kinetic molecular theory?
There is no difference, they are the same.
