Answer is: elements in the same group have similar chemical properties.

Periodic law is the arrangement of the elements in order of increasing atomic number.

For example all alkaline metals (I group of periodic table, Na, K, Cs ...) loose one electron in chemical reaction and react vigorously with water.
