But there is a bit of a problem, in that the two descriptions of the nucleus of an atom don't sit too well together.

A new milestone in nuclear physics has been achieved with the direct observation of three different deformations in the ...

A team of researchers from GSI/FAIR, Johannes Gutenberg University Mainz, and the Helmholtz Institute Mainz has succeeded in ...

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 ...

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 ...

The atom is a complex system of particles. It's made up of a central nucleus consisting of protons and neutrons, called ...

After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all its mass, and positive charge, in a central nucleus about 10,000 times smaller than ...

In 1919 Rutherford had discovered the proton, a positively charged particle within the atom's nucleus. But they and other researchers were finding that the proton did not seem to be the only ...

This summer, UCLA physicists succeeded in getting the nucleus of a thorium-229 atom embedded in a transparent crystal to absorb and emit photons like the electrons in an atom do, ending decades of ...

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 ...
