Lithium compounds are slightly covalent because of its greater ............. . Complete the statement .

Explanation

**Step-by-Step Solution:**

1. **Understanding Covalent Compounds**: Covalent compounds are formed when atoms share electrons. The nature of the bond can be influenced by the size of the ions involved.

2. **Phazan's Rule**: According to Phazan's rule, the covalent character in a compound increases when the cation is small and the anion is large. This is because a smaller cation can exert a stronger attractive force on the electrons of a larger anion.

3. **Polarizing Power**: The ability of a cation to distort the electron cloud of an anion is known as its polarizing power. A smaller cation has a higher charge density, which means it can polarize the anion more effectively.
