Question

Down the group___________ remain same

Answer 1

• 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
