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 element's atomic number defines it. An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons ...

In his Inaugural Address, Trump credited Americans with splitting the atom, an achievement credited by many to pioneering physicist Ernest Rutherford of New Zealand.

For almost a century, measurements have indicated that a significant proportion of matter in the universe consists of unknown ...

"Rutherford's ground breaking research on radio communication, radioactivity, the structure of the atom and ultra sound technology were done at Cambridge and Manchester Universities in the UK and ...

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 ...

This electronic structure determines many of the defining characteristics of an atom or molecule, including their chemical, optical, and electrical properties. Quantum simulations of chemistry and ...
