Lithium and beryllium are unique in such a way that they have higher charge densities which produce strong polarizing effects due to:
Correct answer: A. Small size
- A. Small size
- B. High electronegativity
- C. Low ionization energy
- D. Large atomic radius
Explanation
Lithium and beryllium's small size and high charge density cause strong polarizing effects, leading to covalent bond formation and their unique properties.

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.
