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...
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...
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.
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.

Refers to different atomic forms of all elements in contrast to ?isotopes?, which refer only to different atomic forms of a single element.

A region in which the probability of finding an electron is zero.

A substance that cannot be decomposed into simpler substances by chemical means.

A measure of the intensity of heat, i.e. the hotness or coldness of a sample. or object.

The number (6.022x10^23) of atoms, molecules or particles found in exactly 1 mole of substance.

Substances consumed in a chemical reaction.

Energy that matter possesses by virtue of its position, condition or composition.

Radius of an atom.

The number of moles of a component of a mixture divided by the total number of moles in the mixture.

Equation that results from canceling spectator ions and eliminating brackets from a total ionic equation.
