Periodic table of chemical elements of Mendeleev online calculator


Interactive grid that will help you to learn more about any element in the periodic table of chemical elements of Mendeleev.
Our interactive periodic table of chemical elements, calculate the atomic number, atomic mass, melting point, freezing point, the boiling point of each element.
Periodic table, she (the periodic system of chemical elements) is a table which classifies the chemical elements by different properties, depending on the charge of the atomic nucleus.
This system expresses in the form of a table, the periodic law of chemical elements, which in 1869 was opened by Russian scientist chemist D. I. Mendeleev.
The first version of the table was developed by Mendeleev in the years 1869-1871, he determined the dependence of the properties of the chemical elements, atomic masses (then called atomic weights).
It was suggested several hundred different variants of the image properties of the chemical elements from the analytical curves of graphs, and to various geometric shapes, but scientists eventually agreed that the most convenient option is to image a two-dimensional table in which each column will indicate the physico-chemical properties of a particular element, and the periods of the elements close to each other, will determine the row of the table.
