The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. This ordering shows periodic trends, such as elements with similar behaviour in the same column. It also shows four rectangular blocks with some approximately similar chemical properties. In general, within one row (period) the elements are metals on the left, and non-metals on the right. The "Atomic Table" app presents the periodic table elements with following details for each of the elements- Atomic number Symbol Atomic weight Category Group, period, block Electron confihuration Electrons per shell Density Melting point Boiling point Specific heat Electro-negativity Abundance Common isotopes The periodic table accurately predicts the properties of various elements and the relations between properties. As a result, it provides a useful framework for analyzing chemical behavior, and is widely used in chemistry and other sciences.
