This attraction pulls the atoms together. The electrons end up being shared by the atoms in a region around the nucleus of both atoms. Hydrogen atoms are close together. The electron from each atom ...

As you can probably infer from rubbing a balloon on your head, your kid touching your hand as they get off a trampoline, or ...

J. Thomson’s discovery that atoms were not indivisible, but contained smaller, negatively charged entities called electrons — the first subatomic particles to be identified. Then, in 1911 ...

In a first, physicists have directly seen Hofstadter’s butterfly—a long-sought-after fractal in the quantum realm ...

Think about atoms -- the building blocks of everything around us. Sometimes, they lose their electrons and become charged particles (that's ionization). It happens in lightning, in plasma TVs ...

The n-type silicon is made by including atoms that have one more electron in their outer level than does silicon, such as phosphorus. Phosphorus has five electrons in its outer energy level, not four.

"Muonic atoms are really fascinating," Dr. Smits said. "A muon is a heavy version of the electron and can be produced by cosmic rays or in the lab. "They can orbit the nucleus just like electrons ...
