Basicity is inversely proportional to
Correct answer: D. A and C
- A. Charge on ion
- B. Size of metal
- C. Charge/size
- D. A and C
Explanation
Basicity is the ability of a substance to accept a proton. This ability is inversely proportional to the charge on an ion and the charge/size ratio. A higher charge on an ion increases its attraction to existing protons, making it less likely to accept additional ones, thereby reducing basicity. Similarly, a higher charge/size ratio increases the charge density, which also decreases the ability to accept more protons.Option B, the size of the metal, is not inversely proportional to basicity in a straightforward manner. Larger metals can sometimes increase basicity because their valence electrons are more easily accessible for bonding.

About Reactions of Group II Elements
Group II reactions cover the behaviour of beryllium, magnesium, calcium, strontium and barium with water, oxygen, halogens, acids and nitrogen. The trends in reactivity, hydroxide solubility and basicity, along with the thermal decomposition of carbonates and nitrates, depend on increasing atomic size down the group.
