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

Seven years ago, a scientist accomplished what no one else had before: capturing an image of a single atom. This stunning ...

Beyond the simplistic models of protons and neutrons clustered together like gumballs in a dispenser, the nucleus of a ...

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

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 ...

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.

The simple reason is that it takes much more energy to excite a nucleus into a higher energy state than it does an atom. Atomic clocks typically excite cesium atoms with photons of energy 4 x 10-5 ...

As if searching for dark matter isn't difficult enough already, physicists may have detected another hurdle known as a ...
