Chemistry Periodic Table - 7

The Chemistry Periodic Table and Its Use

Introduction

The periodic table is an arrangement of chemical elements in tabular form. The chemical elements are ordered by their own electron configuration, recurring chemical properties and atomic number which are the number of protons. The ordering reveals periodic trends like elements with behaviour of same similarity in the same column. The periodic table also reveals four rectangular blocks with some similar chemical properties. Basically, within a row, the elements on the left are metals and those on the right are non-metals.

Features Of The Chemistry Periodic Table

The rows that are in the table are regarded as periods. The periodic table also has columns that are regarded as groups. Just six groups are named so also the numbers. For example, group seventeen elements are regarded as halogens. While group 18 are regarded as noble gases. The periodic table could be used to ascertain the relationship and connection between the properties of the elements and make a prediction of the properties of new elements that have not be discovered. Periodic table helps in providing a platform for analyzing chemical behavior. It is very much used in chemistry.

Elements that have atomic numbers from 95-118 have been synthesized in nuclear reactors and laboratories. The synthetic of elements that have higher atomic numbers is being chased. Various synthetic radionucles of elements that occur naturally have been produced in laboraties too

Each chemical element that is represented on the chemistry periodic table has a distinct atomic number. This distinct atomic number represents the number of protons in the nucleus of the chemical element. Most of the elements possess different number of neutrons amidst diverse atoms,with the variants being tagged as isotopes. For example, carbon possesses 3 isotopes and all of its atoms possess 6 protons. It should be noted that most of them have 6 neutrons too and also a small amount possess 8 neutrons. Isotopes in periodic tables are never separated. They are usually put in the same single element. Elements that have no stable isotopes usually have atomic massess of their stable isotopes, where the masses are revealed in parentheses.

Conclusion

In a chemistry periodic table, the elements are shown in the order of the elevating atomic number.
