diagonal relationship

Question

Diagonal relationship observed between Li and Mg due to:

RankGuru · Accepted Answer

1. **Definition**: Elements of the second period sometimes show similarities to elements of the third period in the next group.
2. **Compensating Trends**: 
   - Moving right across a period: Size decreases, electronegativity increases.
   - Moving down a group: Size increases, electronegativity decreases.
3. **Result**: These two opposing changes effectively cancel out when moving diagonally.
4. **Specifics**: $Li$ and $Mg$ have very similar **ionic radii** ($0.76$ Å and $0.72$ Å) and comparable **charge/radius ratios (polarizing power)**.
5. **Impact**: They share chemical properties like formation of nitrides and similar solubilities of carbonates.
