 Mendeleyev periodic system put forward before the discovery of the theory of atomic structure, ie subatomic particles. Constituent particles of atomic nuclei are protons and neutrons, while the electrons circling the nucleus of an atom. After a subatomic particle found, it turns out there are some elements 

that have the number of particles of protons or electrons the same, but different numbers of neutrons. These elements are known as isotopes. So, there are atoms that have the number of protons and the same chemical properties, but different mass because the mass of protons and neutrons determine the mass of the atom.

 In 1829, Johan Wolfgang Dobereiner, a chemistry professor in Germany, pointed out that the relative atomic mass Strontium is very close to the average mass of the two other elements that are similar to strontium, namely calcium and barium. Dobereiner also find some other elements such groups. Therefore, Dobereiner conclude that the elements could be grouped into groups of three elements which he called Triade. However, Dobereiner have not managed to show enough so that the rule Triade helpful.

 In 1866, John A.R Newlands British chemist suggested that elements arranged in order of atomic mass ascension has properties that will be repeated every eighth element. That is,

 .

The elements in the modern periodic system table compiled based on the increase in number of atoms. Because of the periodic system composed long form, then the periodic table which is now called the long periodic table. Sometimes also called the modern periodic table, because compiled by the concepts that have been modern.

 Unlike the Mendeleyev periodic table, because of the short form, it is often called short periodic system. In the long form of the periodic system, the nature of the elements are periodic functions of their atomic numbers. This means that the properties of elements depend on the atomic number.Periodicity properties of elements in order of atomic mass ascension every multiple of eight so-called law of octaves. At that time, the newly discovered 60 elements. The noble gases are not included in the classification system for undiscovered octaves.
