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 ...

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 ...

Of all the subatomic particles that have any mass at all, the neutrino is the lightest by far. In comparison, the electron, itself a quantum featherweight, has a mass that is at least 500,000 times ...

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.

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 ...

The building blocks of matter that have been experimentally verified are the quarks and leptons described by the Standard Model. Since the discovery of the electron in 1897, physicists have identified ...

A new study suggests that the positively charged particles may have an outsize influence on the properties of neutron stars and other neutron-rich objects. Neutron stars are the smallest, densest ...

This lesson utilizes an adaptation of the board game Subatomic: An Atom Building Game to help students learn about the different parts that make up an atom. During their turn, players can choose to ...

An ancient crocodile’s last meal might never have come to light were it not for researchers deciding to scan the rock-embedded fossil with a beam of neutrons. The scientists had set out to see if ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...
