Whether hung on classroom walls, put up in dorm rooms or screen-printed on T-shirts, the periodic table of elements screams, “Science!” like no other image. And why not? At 118 members and counting, ...

An element's atomic number defines it. An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So ...

According to the classical model of nuclear structure, the internal structure of nucleons should not change if they are bound into atomic nuclei. But it was discovered 35 years ago that quarks inside ...

Mrs Roberts: What do you think you're made of? Mr Spellman: Big question. Grit, determination, hard-working, handsome, charming, funny. Mrs Roberts: Well, I guess. But you're actually made of atoms.

This video explores the fundamental components of an atom, including protons, neutrons, and electrons, challenging the traditional model that depicts electrons as orbiting the nucleus. It highlights ...

Physicists have known for decades that particles called gluons keep protons and neutrons intact—and thereby hold the universe together. Yet the details of how gluons function remain surprisingly ...

Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

Physics Professor Manuel Calderón de la Barca Sánchez and his students are using the largest and most complex machine ever built to probe the strongest force in nature at the tiniest of scales. “In a ...

There are few things in the Universe that are as easy to form, in theory, as black holes are. Bring enough mass into a compact volume and it gets more and more difficult to gravitationally escape from ...

A research team at the Facility for Rare Isotope Beams (FRIB) is the first ever to observe a beta-delayed neutron emission ...
