Chemistry Periodic Table

Chemistry Periodic Table:




A tabular arrangement of the elements according to their atomic numbers so that elements with similar properties are in the same column. or else that can be arranged in a table of the elements, arranged in order of increasing atomic number, based on the periodic law. Elements having similar chemical properties and electronic structures appear in vertical columns,which take place major role in this atomic structure that defined an equal way that can evaluate in similar elements which determined as follows



Chemical Series of the Periodic Table:

Alkali metals Alkaline earthsLanthaniods Actinoids Transition metals

Poor metals Metalloids Nonmetals Halogens Noble gases

Dmitri Mendeleev invented the first version of the periodic table of elements by doing all this in the periodic table has been predicted the properties of elements yet to be discovered on those days with sevaral many practices occurs in his life. during all these days Mendeleev made other important contributions to chemistry a fruitful researcher in the fields of hydrodynamics, meteorology, geology, certain branches of chemical technology for examples explosives, petroleum, and fuels,e.t.c; Mendeleev studied petroleum origin and concluded hydrocarbons are abiogenic and form deep within the earth what are depths are taken place which have more and more researches at that place occurs and some days later petroleum was in deep depths inner of the earth that's causes he say about this by long way researches they had at those times he understand that the petroleum was born in the depths of the earth.
He is only roll modal to all scientist at that time then he says about periodic table is a tabular display of the chemical elements, organized on the basis of their atomic numbers, electron configurations, and recurring chemical properties.
