What makes lithium to show properties uncommon to rest of the alkali metals?

Explanation

To understand why lithium exhibits properties that are uncommon compared to other alkali metals, we can analyze the factors that contribute to its unique behavior. Here’s a step-by-step breakdown of the explanation:

### Step 1: Small Atomic Size
- **Explanation**: Lithium has a smaller atomic size compared to other alkali metals (like sodium, potassium, etc.). This small size is significant because it affects various properties of the element.

### Step 2: High Polarizing Power
- **Explanation**: Due to its small size, lithium has a high polarizing power. Polarizing power refers to the ability of a cation to distort the electron cloud of an anion. Since lithium is small, its positive charge is concentrated in a smaller volume, leading to a stronger attraction to anions.
