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 ...

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 ...

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical billiard balls and more like quantum actors. A growing body of research now ...

First 20 Elements Of The Periodic Table: The atomic number and symbols are important in chemistry. The atomic number of elements gives us an idea about the atomic structure of elements, such as how ...

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 ...

Atoms are very small. They have a radius of around 1 × 10 10 metres. This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons), 17 of which are protons. It also tells us ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...

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

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 ...

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 ...

Are you real? You may seem real and solid, but you are mostly made of empty space. To demonstrate it, someone enlarged an electron to the size of one pixel, proportionally showing its distance from a ...

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, ...
