The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called ‘groups’ and the horizontal rows are called ‘periods’. The modern periodic table is based on the modern periodic law put forward by the English physicist Henry Moseley, which states that “the properties of ...
