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.

Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...

Use of diamonds
Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most...

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.

Cloud Chamber
A device for observing the paths of speeding particiles as vapor molecules condense on them to form foglike tracks.
Boiling Point
The temperature at which the vapor pressure of a liquid is equal to the applied pressure, also the condensation point
Strong Field Ligand
Ligand that exerts a strong crystal or ligand electrical field and generally forms low spin complexes with metal ions when possible.
Octane Number
A number that indicates how smoothly a gasoline burns.
Molecular Geometry
The arrangement of atoms (not lone pairs of electrons) around a central atom of a molecule or polyatomic ion.
Metathesis Reactions
Reactions in which two compounds react to form two new compounds, with no changes in oxidation number. Reactions in which the ions of two compounds exchange partners.
Differential Scanning Calorimetry (DSC)
A technique for measuring the temperature, direction, and magnitude of thermal transitions in a sample material by heating/cooling and comparing the amount of energy required to maintain its rate of temperature increase or decrease with an inert reference material under similar conditions.
Polyprotic Acid
An Acid that can form two or more hydronium ions per molecule, often a least one step of ionization is weak.
