Detailed explanation-1: -The physical and chemical properties of elements depend on the number of valence electrons. Elements present in the same group have the same number of valence electrons. Therefore, elements present in the same group have similar physical and chemical properties.
Detailed explanation-2: -All the members of a family of elements have the same number of valence electrons and similar chemical properties.
Detailed explanation-3: -The elements in the same group have similar chemical properties because they have the same valence shell electron configuration. The elements in a row show a gradual change in chemical properties because their valence shell electron configuration changes gradually along the row.
Detailed explanation-4: -Elements with the same number of valence electrons have similar chemical properties.
Detailed explanation-5: -Elements within the same group have the same number of electrons in their valence (outermost) shells, and they have similar electron configurations. They exhibit similar chemical properties.
