How would you explain the lower atomic radii of Ga as compared to Al ?

Among the statements (I -IV) , the correct ones are : (I) Be has smaller atomic radius compared to Mg. (II) Be has higher ionization enthalpy than Al. (III) Charge/ radius ratio of Be is greater than that of Al. (IV) Both Be and Al form mainly covalent compounds.

The nuclear radius as compared to the atomic radius, is of the order of

Consider two rings of copper wire. One ring is scaled up version of the other, twice large in all regards (radius, cross sectional radius). If current around the rings are driven by equal voltage source then choose the CORRECT alternative(s). Assume that cross-sectional radius is very small as compared to radius of rings :

(a) Both assertion (A) and (R) are true and reason (R) is the correct explanation of assertion (A). (b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A). (c) Assertion (A) is true but reason (R) is false. (d) Assertion (A) is false but reason (R) is true Assertion (A) : Herbivores have larger small intestine as compared to carnivores. Rason (R) : Complete digestion of food takes places in small intestine.

Assertion: Aquatic herbivores are usually more productive as compared to terrestrial herbivores. Reason: Phytoplanktons achieve faster grwoth rate and more nutritous to heterotrophs than their terrestril counterparts due to their small size and lack of structural tissues.
