Explanation
The periodic table is a tabular arrangement of chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties. Elements are presented in order of increasing atomic number. Columns in the periodic table are called groups, and rows are called periods. There are 18 groups and 7 periods in the periodic table. The table is termed "periodic" because the elements show periodic recurrence of similar properties as the atomic number increases.
