The game give a tool that can control the voltage and control the the electron trajectory, so the player can understand how the electric interacted with the electron.

Atoms To Go is the complete software periodic table of the elements. In addition to the usual information, Atoms To Go also contains a wealth of nuclear information on each isotope, including half life, decay mode, and daughter products. There's a handy chart of the nuclides, showing all of the isotopes, about 1600 of them. Clicking on one takes you to detailed data for that isotope, such as half life, decay mode, alpha/beta/gamma energies, and daughter products. A molecular weight calculator makes it easy to find the molecular w...

Free-Electron Lasers (FEL) are novel devices where unlike conventional lasers the wavelength can be freely chosen by the energy of electron beam injected into the periodic magnetic field of an undulator. The physics of the FEL can be described by a simplified model, which allows to estimate the required length, the output power and other related information about the performance.

Why are some triatomic molecules linear (carbon dioxide, hydrogen cyanide) and others are bent (water, sulfur dioxide)? And why is the bond angle in water (~105°) smaller than that in sulfur dioxide (~119°)? Valence Shell Electron Pair Repulsion (VSEPR) theory provides surprisingly simple explanations in terms of the electron pairs that surround the central atom of a given molecule. VSEPR theory is described in detail in every introductory chemistry book. The ODYSSEY VSEPR Theory app provides three-dimensional models of 50 small m...
