The Complete Periodic Isotopic and Table of Elements Explained

ADVERTISEMENT

The first successful periodic table of elements created by Russian chemist Dmitri Mendeleev is a common tool in the field of science. All the chemical elements have been grouped in a tabular form in this periodic table based on their atomic number, electronic configuration and their similarity in chemical properties. Mendeleev periodic table specified the recurring trends or periodicity in the properties of the elements. This is well explained in the best periodic table of elements books available in the market. 

The United Nations has entitled the year 2019 as the International Year of The Periodic Table of Elements to celebrate this important tool to the world of science. This is because the use of the periodic table of the elements in 2019 is not only limited to chemistry but widely utilised by the professionals from other fields including biology, physics and more.

Many effective books and tools are currently found that make the learning and comprehending the periodic table of the elements in 2019 simple and easy. Students, teachers and individuals interested in chemistry, especially find them quite beneficial to know about the chemical elements in a detailed way. 

To have a better understanding of the chemical elements, let us explain the complete periodic isotopic and table of elements below.  

An Overview of the Periodic Table of Chemical Elements

The periodic table displays 118 chemical elements with seven rows known as periods and columns, termed as groups. The left side consists of the metals while the non-metals are placed on the right. Six groups have been named and assigned numbers, such as halogens (group 17) and noble gases (group 18). 

There is unique atomic number (Z) of each chemical element that represents the number of protons in its nucleus. Many elements come with different number of neutrons in various atoms. These variants are referred to as isotopes. For instance, there are three naturally occurring isotopes of carbon with six protons and six neutrons in most of its atoms. However, about one percent of atoms of carbon consist of seven neutrons and a small fraction of them consist of eight neutrons. 

The periodic table has not been arranged according to the various isotopes of an element but always placed under a single element. The elements that do not have stable isotopes have the atomic masses similar to their most stable isotopes and such masses are listed in parentheses in the periodic table.  

The standard periodic table contains elements that are listed per their increasing atomic number, which is the number of protons present in the nucleus of an atom. A new row or period begins when a new electron shell has its first electron.

On the other hand, the electronic configuration of an atom determines the columns or groups. The elements with the same number of electrons in a specific subshell and similar chemical properties are arranged in the same column. This is simply a gist of the complete periodic isotopic and table of elements that will give you an idea about the periodic table and the chemical elements.

In Conclusion

For full understanding of the periodic table you can turn to the best periodic table of elements books and go through them in a precise way. As mentioned above, there are unique sets of periodic table of elements that make your learning of chemistry far more interesting and simple.
