No two electrons in an atom can have identical quantum numbers. This is an example of a general principle which applies not only to electrons but also to other particles of half-integer spin ...
Description of radioactive process of electron capture with good links to other sites.
Many features of the dynamics of free electron lasers can be understood using a simple pendulum model. This site uses JAVA applets to demonstrate this.
A simple illustrated explanation of what is an electron microscope and the difference between resolution and magnification.
Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms, in contrast to the transfer of electrons in ionic bonds.
An introduction to electron spin with links of to other topics such as fine structure.
An illustrated history of J.J.Thomson's discovery of the electron. There is a brief story of Thomson's life, some further developments and links to other web sites and relevant reading.
A convenient energy unit, particularly for atomic and nuclear processes, is the energy given to an electron by accelerating it through 1 volt of electric potential difference.
Ernst Ruska (1906 - 1988) received the Nobel Prize for Physics in 1986 for his fundamental work in electron optics, and for the design of the first electron microscope.
A site for children explaining how the scanning electron microscope works, and showing some images of objects.
