Periodic table:
The periodic table is the arrangement of elements in the increasing order of their atomic number in the tabular format in columns and rows.
The horizontal rows are called ‘periods’ (which go from left to right) and the vertical columns are called ‘groups’ (going from up to down).
A number of elements in the periodic table is 118.
Thus, a periodic table is an arrangement of elements in the increasing order of their atomic numbers in a tabular format.
