The Periodic Table; Getting the Elements Straight in Order.
The periodic table sometimes referred to as the periodic table of elements is an arrangement of all the chemical elements in a tabular representation format. Several aspects and innate properties of the chemical properties of the elements have been taken into account such as atomic number, electron configuration in the individual shells and the innate chemical properties to obtain the periodic table. The periodic table of elements has been so arranged to group elements exhibiting similar chemical properties and reactive behaviour into periodic trends. Consisting of seven periods demarcated by the seven rows of the periodic table, the right-hand side of the table has been allocated to non-metals and the left-hand side having been allocated to metals mostly. The groups demarcated by the eighteen columns group the elements exhibiting similar chemical behaviour. The periodic table is also known to exhibit four distinct colour schemes that mark the way the atomic orbitals of the individual elements are filled.
For years people have been trying to arrange and group the known elements to better understand their properties and utility from a human purview of things. Dmitri Mendeleev, a Russian chemist is attributed as the first person to have successfully designed the periodic table of elements which accurately grouped and described the chemical properties of elements. Mendeleev made sure to even allocate empty spaces within the arrangement for unknown or undiscovered elements. He had made sure to exactly describe what kind of element can take the empty allocated space in the future. Most of his predictions can also be seen coming true upon running a glance through the periodic table.
It is mostly believed the current periodic table contains information about 118 elements which both occur naturally and have been successfully isolated and synthesized in the laboratory, even nuclear reactors. Research and synthesis of elements with higher atomic numbers is an ongoing process which will go on adding more elements as they get discovered. ‘An Attempt Towards a Chemical Conception of the Ether’ was the name of the book, the first periodic table was published in 1869 by Dmitri Mendeleev, a profound contribution by Russia to modern Chemistry.
