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 ...

Mitochondria divide to share the load when nutrients are scarce — plus, how smashing atomic nuclei together helps identify their shapes.

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.

Nuclear fission—when the nucleus of an atom splits in two, releasing energy—may seem like a process that is fully understood.

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

It also tells us that chlorine has 18 neutrons (35 - 17) and, as the number of electrons and protons are equal in a neutral atom, chlorine also has 17 electrons. The relative mass of a nucleus is ...

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

A team of physicists say they have created the first coherent picture of atomic nuclei from their composite particles, quarks and gluons. The 20th century was a pretty busy hundred years for ...

In the past, such events were regarded as 'momentary' or 'instantaneous': An electron orbits the nucleus of an atom—in the next moment it is suddenly ripped out by a flash of light. Two ...

An atom becomes radioactive when its nucleus contains too many or too few neutrons. Try to keep the same number of neutrons and protons as you build your atom. If the imbalance is too great ...
