University of Queensland scientists have cracked a long-standing puzzle in nuclear physics, showing that nuclear polarization ...

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 AMoRE experimental collaboration in South Korea has reported not finding evidence of neutrinoless double beta decay after ...

When two hydrogen atoms get close enough, 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 ...

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 ...

A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom's nucleus. The attraction by chlorine is stronger than the attraction by sodium. An ...

These additions made sense in Bohr’s picture of the atom: if the electron is moving along a circular orbit around the atomic nucleus, it would have an angular momentum; and as a charged body in ...

They have demonstrated that nuclear polarisation does not impede the study of muonic atoms. It clears a major obstacle that ...

University of Queensland researchers have made a breakthrough in muonic atom research, clearing the way for new nuclear ...
