By increasing which of the following factor polarizability increases?
Correct answer: A. Atomic radius
- A. Atomic radius
- B. Ionization energy
- C. Ionic radius
- D. Hydration energy
Explanation
Polarizability usually refers to the tendency of matter, when subjected to an electric field, to acquire an electric dipole moment in proportion to that applied field. Hence, increasing the size of the atom should increase its polarizability. Size of the atom can be increased by increasing the 'atomic radius'.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
