If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical ...

David Hinde receives funding from the Australian Research Council for research into nuclear reactions forming superheavy elements. The hunt for long-lived superheavy elements has taken another leap ...

An atom is the smallest unit of an element that retains its chemical properties. It is made of protons, neutrons, and electrons. (Image: M ...

What’s going on with this silent threat that can stealthily damage your body in ways that can take years to reveal themselves ...

The rare radioactive substance made its way from the United States to Russia on a commercial flight in June 2009. Customs officers balked at accepting the package, which was ensconced in lead ...

Physicists develop a 'nuclear periodic table'. While the traditional table is based on the behavior of electrons in an atom, this new table is based on the protons in the nucleus. Protons have ...

Use a concept map to review atom-related terms. Concept maps are a way to visually show how the parts of a system relate to one another. In a concept map, nouns are used to describe the components of ...

A: Immediately (much less than a second) after the Big Bang, the universe was both too hot and too dense for elements to form. Hydrogen didn’t appear until the universe had spread out — and ...

Scientists say they've created a handful of atoms of the elusive element 115, which occupies a mysterious corner of the periodic table. The super-heavy element has yet to be officially named, but it ...

For now, they're known by working names, like ununseptium and ununtrium — two of the four new chemical elements whose discovery has been officially verified. The elements with atomic numbers 113, 115, ...
