Short answer – nothing. It is the molecules that are made up of atoms that change after death. The atoms are simply rearranged in less ordered ways. This is called decay and, ultimately, entropy.

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 ...

Researchers show that an excited state previously predicted to exist in neon-20 is real by using particle scattering experiments. By merging into five groups of four, the protons and neutrons in ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The story of our cosmic history is one of an expanding and cooling ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

In 1913, Niels Bohr suggested that electrons orbited the nucleus in different energy levels (called shells close shellAn energy level around the nucleus where electrons can be found orbiting.). This ...

A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even ...

Individual protons and neutrons in atomic nuclei turn out not to behave according to the predictions made by existing theoretical models. This surprising conclusion, reached by an international team ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei – the center part of atoms, which make up all matter – were more ...

Osaka, Japan - Scientists from the Department of Physics and the Research Center for Nuclear Physics (RCNP) at Osaka University, in collaboration with Kyoto University, used alpha particle inelastic ...
