प्रश्न
Why do elements in the same group have similar physical and chemical properties?
Advertisements
उत्तर १
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.
उत्तर २
The elements in a group have same valence shell electronic configuration and hence have similar physical and chemical properties.
