- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
- The most expensive metal in the world
Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.
- 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...

Most Popular
Precipitate
An insoluble solid formed by mixing in solution the constituent ions of a slightly soluble solution.
Oxidation Numbers
Arbitrary numbers that can be used as mechanical aids in writing formulas and balancing equations, for single- atom ions they correspond to the charge on the ion, more electronegative atoms are assigned negative oxidation numbers (also called Oxidation states).
Endothermicity
The absorption of heat by a system as the process occurs.
xenon tetrafluoride
A colorless, crystalline compound, XeF4, prepared by heating a gaseous mixture of fluorine and xenon.
Nitrogen Cycle
The complex series of reactions by which nitrogen is slowly but continually recycled in the atmosphere, lithosphere and hydrosphere.
Emulsifying Agent
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
Leveling Effect
Effect by which all acids stronger than the acid that is characteristic of the solvent react with solvent to produce that acid, similar statement applies to bases. The strongest acid (base) that can exist in a given solvent is the acid (base) characteristic of the solvent.
Hydrate Isomers
Isomers of crystalline complexes that differ in whether water is present inside or outside the coordination sphere.
Heterocyclic Amine
Amine in which the nitrogen is part of a ring.
Boron Hydrides
Binary compounds of boron and hydrogen.
