Importance of Periodic Table In Chemistry
The periodic table of elements was invented by Russian chemist Dmitri Mendeleev in 1869, to determine the periodic trends of chemical elements. Mendeleev is also regarded as the Father of Periodic Table. It is a table which shows the arrangement of chemical elements in the form of a table arranged by their atomic numbers in the ascending orders arranged in columns and rows. The periodic table was discovered by chemists and is based on the electronic structure of the elements as explained in Physical Chemistry.
All the elements in the periodic table are arranged in the groups & periods. The vertical rows of elements are arranged in such a way that the elements of same chemical property fall in the same column displayed in different colours to demarcate. The elements can be alkali metals, alkali earth metals, halogens and noble gases. The horizontal row represents the elements in periods; those having property of same kind. One can find the element in the table using its atomic number. Once located you can even categorize and guess the chemical properties, number, mass and valency of the element also. The periodic table was changed by the IUPAC (International Union of Pure and Applied Chemistry) in December 2010. The changes were made in the weights of Carbon and Hydrogen lately.
The periodic table is found to be of great use to the Chemistry Graduates. The Periodic Table is used for to organize elements into categories based on the way they react when combined with others. When a chemistry student looks at the periodic table, he can find the elements arranged from left to right and top to bottom in ascending atomic number. A chemist can compare the families of the element s based on the number and mass of the element. The tables are also used to carry out various chemical calculations.
