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 ...

Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear ...

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 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 ...

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, ...

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.

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 ...

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 ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The big idea of atomic theory is that, at some smallest, fundamental ...

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 ...
