A team of physicists say they have created the first coherent picture of atomic nuclei from their composite particles, quarks ...

Nuclear fission, discovered in 1938, involves splitting an atom's nucleus, releasing energy. It's essential for electricity ...

What’s the safest place to store important information? No, it’s not your external hard drive or some secret cloud ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic ...

On New York's Long Island, scientists are building an ambitious machine to tease apart the mysteries held inside atomic ...

the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up being shared by the atoms in a region around ...

A class of material called perovskites, which have special electronic bonding with many applications, could be useful for ...

Number of protons Z = 30 Number of protons + neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...

An atom becomes radioactive when its nucleus contains too many or too few neutrons. Try to keep the same number of neutrons and protons as you build your atom. If the imbalance is too great ...

Texas A&M University professor Peter McIntyre and his colleagues want to build a particle accelerator around the rim of the ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...
