All the elements in the same group have similar chemical properties.

Explanation:

In a periodic table, elements are arranged in 18 vertical columns known as groups and 7 horizontal rows known as periods.

Elements arranged in a group show similar chemical properties because of the presence of same number of valence electrons.

For Example: Sodium and potassium react with water vigorously as they belong to same group which is Group 1.
