We explore the science and chemistry going on inside Theo Gray's periodic table table. Step into his office, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells ...

At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature. In fact, they ...

The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could successfully predict their masses, densities, how they would link up with other ...

We're all familiar with the elements of the periodic table, but have you ever wondered what hydrogen or zinc, for example, might sound like? W. Walker Smith, now a graduate student at Indiana ...

Editor’s Note: This story is part of CNN’s coverage of Black History Month and its ongoing commitment to honoring unsung heroes. While other seventh graders hung ’90s pop band and movie posters on ...

Researchers have directly observed the heaviest atom yet participating in a chemical reaction and forming a molecule. The finding pushes “superheavy” chemistry, which involves extremely massive ...
