Solution

Chemical properties of an element depend upon the valence electrons.
In the modern periodic table elements which have similar chemical properties are placed in the same group.
Chemical properties of all elements belonging to the same group are the same because they have the same valence electrons.
As we move downward in the group, valence electrons remain the same.
Down the group, valence electrons remain the same
