Major phases in the history of theories and views about the structure of the atom.
The process of the decay of unstable nuclei is called radioactivity.
The atomic bomb is one of the most destructive weapons in human history.
Energy released during nuclear fission can be used for civilian or military purposes.
In benzene there are sigma bonds and delocalised pi bonds between carbon atoms.
This animation shows the electron configuration of the calcium atom.
Nuclear fusion will serve as an environmentally friendly and practically unlimited source of energy.
Lasers are devices designed to emit narrow, monochromatic, high-intensity beams of light.
Marie Curie, the only person to win the Nobel Prize in two different sciences, is probably the most famous woman in the history of science.
Nuclear power plants convert the energy released during nuclear fission into electric power.
This animation demonstrates the structure of nitrogen molecules, with one sigma and two pi bonds holding the atoms together.
The Rutherford Experiment proved the existence of positively charged atomic nuclei. The results led to the elaboration of a new atomic model.
The diameter of the Sun is about 109 times that of the Earth. Most of its mass consists of hydrogen.
