The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

As the nucleus splits, it also releases its neutrons. These neutrons bounce around at incredible speeds until some eventually ...

The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead-208 with ...

When it comes to talent, versatility and the power to change the world, which atomic particle is the champ? Read what our four contenders have to say—then you decide. Physics fans, are you ready to ...

The stuff you scrape off burnt toast is made primarily of atoms of carbon. But what makes up a carbon atom—or any other atom? The first subatomic particle to be identified was the electron, in 1898.

and we know that's a very stable combination of protons and neutrons." Related: Why isn't an atom's nucleus round? Helium nuclei, also known as alpha particles, are spontaneously emitted from heavier, ...

A new study reveals that a high degree of gluon fluctuation -- a kind of flickering rearrangement in the distribution of gluon density within individual protons -- could help explain some of the ...

A pair of physicists announced the discovery of a subatomic event so powerful that the researchers wondered if it was too dangerous to make public. The explosive event? The duo showed that two tiny ...

Elementary particles are the smallest known building blocks of the universe. They are thought to have no internal structure, meaning that researchers think about them as zero-dimensional points that ...

No one knows–because neither the human eye or brain is equipped to see it. That’s where art comes in. There’s an invisible world that operates all around us, but we can’t see it. It’s a world composed ...

Wolfgang Pauli, the Austrian physicist who predicted the neutrino’s existence, also won a Nobel, but not for the neutrino (he did a lot of other very important stuff). He might have won for the ...

At Oak Ridge National Laboratory in eastern Tennessee, physicist Leah Broussard is trying to open a portal to a parallel universe. She calls it an “oscillation” that would lead her to “mirror matter,” ...
