Which outcome results when atomic radius decreases in Group 1 cations?

A)Increased polarization of electron cloud
B)Decreased ionic character of bond
C)Electron shielding becomes more complete
D)Electronegativity difference reaches zero

💡 Explanation

Decreased atomic radius generates higher polarizing power. The cation distorts the anion's electron cloud via the **polarization** mechanism. Therefore, polarization will increase, rather than other properties changing without this key mechanism occurring.
