The 1 cent stamp of the set includes a portrait of Rutherford along with a diagram of the Rutherford atomic model, which – correctly – envisaged electrons surrounding a dense central nucleus. The ...

THE beautiful conception which inspires and co-ordinates practically the whole of modern atomic physics is the atomic model of Rutherford and Bohr. Its essential feature-the nucleus-was first put ...

They had witnessed the atomic equivalent, as Rutherford later described it, ... At first, no one seemed to notice the dramatic ramifications of the new atom model.

One hundred years ago, Ernest Rutherford decided to shoot some stuff at atoms and toppled then-current atomic theory. Physicist and blogger Rhett Allain walks through the rise of six atomic models.

Bohr’s atomic model was utterly revolutionary when it was presented in 1913 but, although it is still taught in schools, it became obsolete decades ago. However, its creator also developed a ...

Ernest Rutherford is one of the notable personalities in Science for his contributions to physics. ... he proposed an atomic theory where he tried to describe the structure of atoms.

Over the years other investigators refined Bohr's theory, but his bold application of new ideas paved the way for the development of quantum mechanics. Bohr went on to make enormous contributions to ...
