Solution:
The above statement is true.The elements that make up each group in the periodic table all have the same outer shell electrical configuration. The group's elements share several chemical characteristics. It is because both of their atoms' highest occupied energy levels have an equal amount of electrons. Therefore, an element's quantity of valence electrons determines its physical and chemical characteristics. Moreover, the number of valence electrons shared by elements belonging to the same group is constant. As a result, the physical and chemical characteristics of elements belonging to the same group are comparable.
