Pauli Exclusion Principle
No two electrons in the same atom may have identical sets of four quantum numbers.
Bubbles
Have you ever noticed that soap bubbles go up in winter and fall down in summer? The reason is that warm air is lighter than cold. And in winter the difference between the air temperature in the room (especially near the windows) and the one you exhale into the bubble is enough to overcome the heaviness of its shell.
Enzyme
A protein that acts as a catalyst in biological systems.
Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types.
The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The device is based on a complex process of "tunneling" electrons between the material and the tip of a probe.
Ternary Compound
A compound consisting of three elements, may be ionic or covalent.
