SCIENCE is steadily becoming severely specialised. The proportion of amateurs (in the restricted sense of the word) among original workers of all ranks decreases slowly but surely. The average ...

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 ...

Relativistic electrons can produce transition and Cherenkov radiation, which can excite the waveguide modes of a structure — potentially ... impurities with single-atom resolution.

The attraction by the chlorine atoms is stronger than the attraction by the calcium atom. Two electrons are transferred from the calcium atom, one to each chlorine atom. Calcium becomes a +2 ion and ...

Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly the same consistency throughout, with negatively-charged electrons scattered about in it like raisins in a pudding.

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 ...

Studying the structure of the atom on smaller scales and being able to produce particles with higher masses is what drove the development of accelerators with ever-higher energies. In a ...

Imagine building a Lego tower with perfectly aligned blocks. Each block represents an atom in a tiny crystal, known as a ...
