  • Varieties of garnet minerals

    The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

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.

Cell Potential

Potential difference, Ecell, between oxidation and reduction half-cells under nonstandard conditions.

 

Polar Bond

Covalent bond in which there is an unsymmetrical distribution of electron density.

Atomic Number


Integral number of protons in the nucleus, defines the identity of element.
 

Homogeneous Equilibria

Equilibria involving only one species in a single phase. For example, all gases, all liquids or all solids.

Semiconductor

A substance that does not conduct electricity at low temperatures but does so at higher temperatures.

Law of Conservation of Matter

There is no detectable change in the quantity of matter during an ordinary chemical reaction.
