Ever since the nucleus of the atom was discovered in 1911, scientists have split, fused and smashed nuclei together to unravel its internal structure. Among the numerous researchers worldwide who are ...

A computational model of the more than 26 million atoms in a DNA-packed viral capsid expands our understanding of virus structure and DNA dynamics, insights that could provide new research avenues and ...

IN a letter to this journal last week, Mr. Soddy has discussed the bearing of my theory of the nucleus atom on radio-active phenomena, and seems to be under the impression that I hold the view that ...

Students use the terms isotope, atomic number, mass number, and atomic mass. Atomic Theory: Structure of the Atom: Students use the terms isotope, atomic number, mass number, and atomic mass to ...

Tough, ultralight foam of atom-thick sheets can be made to any size and shape through a new chemical process. In microscopic images, the foam dubbed "GO-0.5BN" looks like a nanoscale building, with ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Most of the mass and all of the positive charge of an atom is in the nucleus. Most of an atom is empty space, (a vacuum). In 1897, ...
