Chemical bond
A chemical bond is the physical phenomenon of chemical substances being held together by attraction of atoms to each other through sharing, as well as exchanging, of electrons -or electrostatic ... > more -
Scanning tunneling microscope
The scanning tunneling microscope or STM, was invented in 1981 by Gerd Binnig and Heinrich Rohrer of IBM's Zurich Lab in Zurich, Switzerland. t is used to obtain images of conductive surfaces at an ... > more -
Quantum tunnelling
Quantum tunnelling (or tunneling) is the quantum-mechanical effect of transitioning through a classically-forbidden energy state. Consider rolling a ball up a hill. If the ball is not given enough ... > more -
Materials science
Materials science is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. It includes elements of applied physics and ... > more -
Wave-particle duality
In physics and chemistry, wave-particle duality holds that light and matter exhibit properties of both waves and of particles. A central concept of quantum mechanics, duality addresses the inadequacy ... > more -
Hydrogen-like atom
Hydrogen-like atoms (or hydrogenic atoms) are atoms with one single electron. Like the hydrogen atom, hydrogen-like atoms are one of the few quantum mechanical problems which can be exactly ... > more -
Acceleration
In physics or physical science, acceleration (symbol: a) is defined as the rate of change (or derivative with respect to time) of velocity. It is thus a vector quantity with dimension ... > more -
Atomic orbital
Atomic orbitals are the quantum states of the individual electrons in the electron cloud around a single atom. Specifically, atomic orbitals are the quantum states of the individual electrons in the ... > more -
Electron configuration
In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary ... > more
