However, when it comes to atoms’ third component, electrons, the answer is not as easy. That’s because, as far as we know, electrons are fundamental particles. In other words, they have no ...

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 ...

Semiconductors are at the heart of most electronics. We explain what semiconductors are, how they work, and just how tiny ...

"Instead of emitting a photon from an injected electron, we inject a photon and watch how the electrons are injected from the illuminated quantum dot to the nearby microbe." While quantum dots ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

Atoms are in fact made up of three smaller particles called protons, electrons and neutrons. The protons and neutrons are contained in the nucleus, the tiny centre of an atom, with smaller ...

To study the interactions between electrons in a material, physicists have come up with a number of tricks over the years. These interactions are interesting, among other things, because they lead ...
