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.

A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other. This attraction holds the atom together. It is ...

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 ...

Recent simulations 10,11 and experiments 12 show that photoionization of a cold atom cloud can produce cold electron bunches with high coherence and current.

Posted: April 16, 2010: In the electron cloud (Nanowerk News) The chemistry between atoms and molecules is strongly determined by their outer electron orbitals, or clouds, which participate in ...

The new images that Banerjee and his colleagues captured show that when graphene is folded or bent, the electron cloud lining its surface also becomes warped, making it more difficult for an electric ...
