The main chemical terms:Aldhrt is a group of objects of finite precision. These objects consist of a positively charged nucleus containing protons Walnytrwnat often, and there are also a number of electrons, equal to the positive charge in the nucleus. The spin of electrons in different levels of known energy levels, where a Alktrwnyn only first level, a level second octet of electrons. The third level is Alktrwna holds 18. Each level power substation has marked by codes s, P, D, f. Wghalbau atoms are Khrbyaan because the number being equal to the number of protons and electrons, the atom can be transformed into positive ion which once lost one or several electrons at the chemical reaction can also be turned into negative ions when they are Alktrwna or more depending on the value of shipment being lost or gained.
Race is a group of atoms which have the same number of protons in the nucleus. This number is called the atomic number of element. For example, all atoms have 6 protons in the nucleus are called carbon atoms of a chemical element, the all atoms have 92 protons in the nucleus are the atoms of an element of uranium. Afdl arrangement and form elements generally exists in the periodic table of elements with similar chemical properties, which are put in the same group. The component name, symbol, atomic number is also described. Almrkb chemotherapy is a material made up of a certain proportion of the elements which determine the installation of boat group that is this compound, which therefore determines the properties of this compound. For example, the water is a compound of hydrogen and oxygen by 2 to 1. The vehicle is formed by chemical reaction. Alshardt (ion) is a compound, or is an atom or molecule has gained or lost electrons, or more. The positive ions are charge Katywnat) such as sodium cation NaNa + negative ions are charge (anion) and anion (CL Cl. When they Athadhma NaCl neutral salt NaCl. Atoms and ions are the many that don't break down during the interactions of acid - base is the hydroxide group (OH), and phosphate (PO43.). Alrwabt chemicals.Chemical bond force between atoms in a molecule or crystal. In many simple compounds, valence theory, the principle of oxidation number can be used to predict molecular structure. Similarly, the theories of classical physics can be used to predict the composition of many ionic compounds. The compounds with a complex structure, such as metal alloys, the equivalence theory can not interpret the structure, this shows the importance of using quantum mechanics theories such as the theory of orbit molecular Bd. Types of chemical bonds: Rabtt Rabtt ionic covalent and metallic Rabtt Wrabtt Tnasqyt and consistency by the covalent bond almost there is another Association a Hydrogen Association and has played a great role in life on earth.
