The matter construction and the properties of the molecules of the matter
The properties of the molecules of the matter
The molecules of the matter are in a continuous motion and there are intermolecular spaces and attraction forces among the molecules of the matter, The kinds of the molecules are the element, the compound and the mixture.
The difference in the molecules of the various substances is found as the result of the difference of the atoms which are involved in the structure of the molecule and depends on the number and the kind of the atoms, and the way of the combination together.
The element molecule
The element is the simplest pure form of the matter which can not be analyzed chemically into the simpler form, The element molecule is formed of the similar atoms (one or more atoms) that combine together.
There are elements molecules that formed of only one atom (The Monoatomic) such as, the solids as (Copper, Iron, Aluminum, Sulphur, Magnesium and Carbon) and the liquids as mercury.
The noble gases such as (Helium, Neon, Argon, Krypton, Xenon and Radon).
There are elements molecules that formed of two atoms (Diatomic) such as
The liquids as bromine.
The active gases such as (Oxygen, Hydrogen, Chlorine, Nitrogen and Fluorine).
|Oxygen molecule is an active gas, and the molecules of the active gases are diatomic.|
The compound molecule
|The compound molecule is formed from different atoms.|
The compound molecule is formed of the different atoms and it is a substance which is formed from a combination of the atoms of two or more different elements with the constant weight ratios.
Examples of compound molecules:
Sodium chloride molecule (table salt), Water molecule, Ammonia molecule, Hydrogen chloride.
