The periodic table has gone through many changes since Dmitri Mendeleev drew up his original table in 1869, yet both the first table and the modern periodic table are important for the same reason: The periodic table organizes elements according to similar properties so you can tell the characteristics of an element just by looking at its location on the table.


The periodic table is one of the most important tools in the history of chemistry. It describes the atomic properties of every known chemical element in a concise format, including the atomic number, atomic mass and relationships between the elements.


The main importance of the periodic table is that it met the need that scientists had to give an explanation to the emergence of the concept of chemical atomism discovered by John Dalton.. The theories and investigations carried out until now were throwing similarities in the atomic mass of some elements, according to their properties.


The purpose of the periodic table is to organize the similarities and properties of the elements in a way that can help us visualize and categorize the materials around us. With one look, we can tell how much each atom weighs, (and the weight of 1...


The periodic table is a system of classifying all the known elements. It is important because it classifies elements by their properties, so the location of an element on the table tells you a lot ...


Elements that lie in the same column on the periodic table (called a "group") have identical valance electron configurations and consequently behave in a similar fashion chemically. For instance, all the group 18 elements are inert gases. The periodic table contains an enormous amount of important information.


The elements on the periodic table is so important in life today, it has helped scientist discover so many big events. The periodic table helped scientist discover what elements were needed for humans to survive.


The importance of the periodic table is that it provides a way of organizing the elements so that it's possible to make certain predictions about their chemical and physical properties based on ...


A Periodic Table is a horizontal arrangement comprising of all the chemical elements that are present in the order of their atomic number, electronic configuration and persisting chemical properties. This ordering represents periodic trends where one row consists of elements that are metals, located to the left of the table and nonmetals to the right.


(1) Systematic Study of the elements Mendeleev’s periodic table was developed in accordance to-(a) increasing atomic masses. (b) grouping of similar elements together. By the way, the study of elements became quite simpler, as if properties of one element in a particular group were known, properties of others could easily be assumed.
