As the metallic radii increases in Group II, the density?

جیسا کہ گروپ II میں دھاتی ریڈی میں اضافہ ہوتا ہے، کثافت؟

Increases

Decreases

Remains the same

Depends upon the elements it reacts with

In Group II (the alkaline earth metals), the metallic radii increase as you go down the group due to the addition of electron shells.
As the radii increase, the mass of the atoms also increases, but the volume increases more rapidly.
This means that the density (mass per unit volume) increases as you go down the group.
