SUMMARY: Electromagnetism is a strong force that causes protons in an atom's nucleus, such as Helium, to repel each other.

This video explores the basic components of an atom—protons, neutrons, and electrons—and discusses the inaccuracies of the ...

HEISENBERG has discussed the hypothesis that the nucleus of an atom is composed of neutrons and protons only, the neutron being regarded as a fundamental entity and not as a combination of an electron ...

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 stable ...

An international team of physicists has developed a new technique that allows researchers to study the interactions between neutrons inside of an atom. In their paper published in the journal Nature, ...

The protons and neutrons that build the nucleus of the atom frequently pair up. Now, a new high-precision experiment has found that these particles may pick different partners depending on how packed ...

Physicists have measured the “skin” of an atom for the first time and, perhaps unsurprisingly, it is extremely thin. The measurement may help us understand the properties of neutron stars. Lead-208, ...

A new study identifies a transition in the strong nuclear force that illuminates the structure of a neutron star's core. Most ordinary matter is held together by an invisible subatomic glue known as ...

For three months in 2019, physicists blasted a beam of electrons at lead atoms that were held in place by foil made of diamond. The team was trying to determine the thickness of the neutron skin, the ...

Whereas some people play extreme sports, many nuclear physicists seek the thrill of extreme isotopes, by finding, for each chemical element, the largest possible number of neutrons that can be held by ...

Since the discovery of radioactivity in the 19th century, humanity has been forced to reckon with an uncomfortable but sobering truth: much of the matter we find today will eventually decay away. This ...
