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.

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...

Ozone
We breathe 24 hours a day, 7 days a week, consuming about 25 kg of air every day. It turns out that we practically predetermine our health by the air we breathe.

Creating Malachite egg
One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

Aromatic Hydrocarbons
Benzene and its derivatives.
Emulsifying Agent
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
Polyprotic Acid
An Acid that can form two or more hydronium ions per molecule, often a least one step of ionization is weak.
Concentration
Amount of solute per unit volume or mass of solvent or of solution.
Nitrogen Cycle
The complex series of reactions by which nitrogen is slowly but continually recycled in the atmosphere, lithosphere and hydrosphere.
Associated Ions
Short-lived species formed by the collision of dissolved ions of opposite charges.
Bond Order
Half the numbers of electrons in bonding orbitals minus half the number of electrons in antibonding orbitals. Bond order gives an indication to the stability of a bond. Also defined as the difference between the number of bonding electrons and antibonding electrons divided by two.
Chemical Kinetics
The study of rates and mechanisms of chemical reactions and of the factors on which they depend.
