Lithium resembles magnesium in some of its properties. Mention two such properties and given reasons for this resemblance.

Explanation

### Step-by-Step Text Solution:

**Step 1: Introduction to the Resemblance**
Lithium (Li) and magnesium (Mg) exhibit similarities in certain properties due to their comparable charge-to-size ratios. This relationship is referred to as a "diagonal relationship" in the periodic table.

**Step 2: Explanation of Diagonal Relationship**
- Lithium is located in period 2 of the periodic table, while magnesium is in period 3.
- The diagonal relationship arises because both elements have similar ionic sizes and charge, leading to comparable chemical behavior.
