Unstable atoms emit fast-moving particles that can damage cells in the human body. Some atoms are far more unstable than ...

In a first, researchers have discovered fragments of Earth's precursor that contain distinctive chemical fingerprints in ...

Scientists found unusual sulfur in moon samples from Apollo 17. The discovery reveals new clues about the Moon’s ancient ...

New studies of the “platypus of materials” help explain how their atoms arrange themselves into orderly, but nonrepeating, ...

The isotopic ratio of sulfur-33 on the moon differs from that of Earth. Did the moon's sulfur instead come from the impactor ...

She co-created the French Atomic Energy Commission in 1945 and held a six-year term, promoting nuclear research and development of the first French nuclear reactor. She later became director of the ...

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 ...

The race is on to harness the near-infinite power of nuclear fusion—by building a star on Earth. And scientists are closer ...

For example, the atomic number of chlorine is 17. Every chlorine atom has 17 protons and 17 electrons. It has 17 positive charges and 17 negative charges, meaning that it is neutral overall. Atoms of ...

Kearny-based Thea Energy partners with AWS to advance stellarator fusion technology, aiming to bring clean, commercial fusion power to market.

In 1992, three physicists began an argument about how many numbers we need to fully describe the universe. Their surprisingly ...

Confining and rotating extremely cold atoms or molecules within atomic “Ferris wheels” made from laser light could test ...
