Periodic table of chemical elements

Periodic table of chemical elements , a demonstration of the chemical elements have been identified based on the electronic structure of ordered Grdydhast a way that many of the characteristics of chemical elements on a regular basis over the table change. The original table without knowing the internal structure of atoms was made: if the elements atomic mass we ordered, and then plots certain other properties of the atomic mass we draw, we can swing or rotation to these properties as a function of atomic mass be. The first person who could see to this regulation, a chemist German named Johann Wolfgang Dvbraynr was. He found a number of elements of the Trinity was the same

Trinity sample‌
Element	Atomic mass	Density
Cl	35.5	1.56 g/L
Br	79.9	3.12 g/L
I	126.9	4.95 g/L
Ca	40.1	1.55 g/cm3
Sr	87.6	2.6 g/cm3
Ba	137	3.5 g/cm3

And followed him, chemist English John Nyvlndz was found that elements of similar type are found at intervals of eight teeth, they can be like music with eight notes, although notes of the law , he was ridiculed by his contemporaries. Finally chemist German Lothar Mir and the Russian chemist Dmitri Mendeleev almost simultaneously developed the first periodic table, arranging the elements by mass, extended (but Mendeleev few elements out of strict mass, respectively, to match better with neighbors properties can be plotted - The later discovery of the electronic structure of elements in the late nineteenth century and the beginning of the twentieth century were justified.) List of elements based on name , symbol and atomic number is available. Periodic table below shows the well-known. Each element with atomic number and chemical symbols. Elements in a column (" Group ") are chemically similar.

Here are other methods for displaying tables are provided: Standard Table - alternative table - the table counter - Big Table - Table massive - Wide Table - Table developed - Table structure - metals and non metals Color code for atomic numbers: Elements numbered colored blue , are liquid at room temperature; Elements numbered colored green , are gases at room temperature; Elements numbered with black, are solid at room temperature. Numbered elements with color red and the combination are not found naturally (all are solid at room temperature.) Numbered elements with color gray , not yet discovered (and are shown as pale as the chemical groups which are placed, to determine. ( And can this keyword periodic table for magnetic resonance find. Number of layers of electrons in an atom determines which row is placed. Each layer is divided into different substrates, each the size of the atomic number increases, the layers as follows: 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p 8s 5g 6f 7d 8p ... Structure of the table are. Since electrons Kharjytryn layer, drawn determine chemical properties, the layers in the same groups Mshabhand. Neighboring elements together in one group, despite significant differences in mass , are isotropic. Elements adjacent to one another in a row with crimes are similar but different properties. For example, very near to nitrogen (N) in the second row of carbon (C) and oxygen (O) are. Despite their similarities in mass (as little in atomic mass units are different), are extremely different properties, as examining other forms can be observed: a diatomic oxygen Kaz shall intensify the burning, diatomic nitrogen, a gas does not exacerbate the burning, and carbon solids that can be burned (yes, we can diamond burnt!). In contrast, very close to the chlorine (Cl) in the last but one table ( halogens ) fluorine (F) and bromine (Br) are. Despite dramatic differences in mass, other forms of their properties are very similar: they are very corrosive (meaning a good tendency to combine with metals to form salts Halayd metal ); chlorine and fluorine are gases, while bromine is a liquid boiling is very low; chlorine and bromine are highly colored.
