Nuclear fission has powered our world and medical advancements for decades. What exactly happens when an atom's nucleus splits into two parts?

A simulation by US theoretical physicists has provided the first fully microscopic characterization of the moment an atom ...

But there is a bit of a problem, in that the two descriptions of the nucleus of an atom don't sit too well together.

Number of protons Z = 30 Number of protons + neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so ...

the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up being shared by the atoms in a region around ...

The atom's nucleus and electrons are held together by the electromagnetic force—the positive charges of the protons balance the negative charges of the electrons. Neutrons have no charge.

Dark matter’s interactions with other matter is impossible to perceive except when it collides with the nucleus of a visible ...

What’s the safest place to store important information? No, it’s not your external hard drive or some secret cloud ...

Researchers have long been hunting for a way to make the elusive elements more stable so they can be better studied.

In 1919 Rutherford had discovered the proton, a positively charged particle within the atom's nucleus. But they and other researchers were finding that the proton did not seem to be the only ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...
