elements with the same group have the same number of valency so they share this property together. And elements with the same number of valency have same chemical property cuz chemical property is determined by electrons.

Elements in the same group have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level. :) Hope this helped!
