Vedclass · Answer

(B) Moving down the group from $Be$ to $Ba$ in alkaline earth metals:$(i)$ Atomic radius increases due to the addition of new electron shells.$(ii)$ Ionisation energy decreases because the valence electrons are further from the nucleus and more shielded,making them easier to remove.$(iii)$ Nuclear charge increases because the number of protons in the nucleus increases as the atomic number increases.Therefore,both atomic radius and nuclear charge increase down the group.

Which of the following properties of the alkaline earth metals increase from $Be$ to $Ba$?
$(i)$ Atomic radius
$(ii)$ Ionisation energy
$(iii)$ Nuclear charge
