Concept Introduction:
The periodic table of an element is the chemical element’s tabular arrangement structured according to their electronic configuration, chemical properties and atomic number. Usually in one period or row towards the left elements are metal and non-metal towards the right having the elements with same chemical properties are kept in the same column. Table column are known as groups and table rows are known as periods.
