Most of the “size” of an atom is just the electron cloud that surrounds the nucleus, and that’s not a solid thing— it will shift around in response to electric and magnetic fields applied ...

If an atom could be enlarged such that we could see it with the naked eye, what would it look like? This question was originally answered on Quora by Dave Consiglio.

Giant atom hides its neighbors under a single-electron skirt Atomic radius expands, pulling neighboring atoms into its warm embrace. Chris Lee – Mar 7, 2018 12:28 pm | 73 ...

The Rydberg atom then contains tens of thousands of atoms from the cold cloud. Thus, the electron is trapped in a defined volume and at the same time interacts with a large number of atoms.

Remarkable molecules whose electron clouds would resemble now-extinct marine creatures called trilobites could appear in experiments on ultracold atom clouds known as Bose-Einstein condensates ...

Physicists generally regard an atom’s nucleus as immune to the tumult of the electron cloud that surrounds it. To excite the nucleus, electrons leaping between energy states would have to emit a ...

Electron Cloud Distributions (IMAGE) ... reveal the weak charge quadrupole of the iron atom, while the blue clouds (fewer electrons) around the outer arsenic ions show weak polarization.
