Atoms (at least atoms larger than beryllium, give or take) are basically a classical particle for all intents and purposes. They have momentum (assuming non-zero temperature) and mass, and basically just keep flying in a direction until they hit something or a force acts on it to pull it in a new direction.

In a solid, the interactions with nearby atoms (through e.g. electrostatic interactions) and the degree to which the atoms are packed mean the ball's basically just vibrating in place.

In a molecule, "bonds" are just forces resulting from electrons being shared that makes it really tough to pull the atoms apart, but they are still basically just balls moving in a direction until they bounce into something, or a force pulls them in another direction.

There's some quantum weirdness about the nature of the forces themselves, but atoms generally behave F=ma just the same as macroscopic stuff.

Three's been talk about using molten salt storage as a way to smooth over the fluctuations from renewables, particularly solar.

The idea is that you'd use the energy from the renewable to heat salt from ~250C to ~500C, and then you'd use the hot salt to heat water to spin turbines. Supposedly the storage would keep for around a week, which is enough to smooth over daily and weekly energy demand fluctuations. It seems like it'd be an easier system to work with than trying to store superheated water, since the salt is a liquid at standard pressure both in the "cold" state and the hot state, but I haven't really heard or seen anything about it since I read about it in like a scientific american or something some 20 years ago.
