So convincing is this model that after only twelve years it is known no longer as “the atomic model of Rutherford and Bohr,” but is simply taken for granted as “the atom.” In this ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is ...

IN a letter to NATURE of November 25 last Dr. Norman Campbell discusses the problem of the possible consistency of the assumptions about the motion and arrangement of electrons in the atom ...

1 The electronic structure of sodium can also be shown in a diagram. Each dot represents an electron. Since the atomic number of oxygen is 8, it will have 8 protons in the nucleus. An atom of ...

Gold nanoclusters—tiny particles composed of from a few to hundreds of gold atoms—are ideal models for studying how atomic ...

In a breakthrough that brings nanoscience one step closer to precise control of chemical reactions, a team of researchers ...

In 1958, British biochemist John Kendrew and colleagues published the first X-ray crystallography-generated atomic structure of a protein: that of myoglobin, a heme-binding protein found in muscle ...

One of the study’s key insights is the influence of hyperfine structure on atomic collisions. Hyperfine structure results ...
