Give the order of the metallic bond strengths in Mg, Ca and Al

Explanation

To determine the order of metallic bond strengths in magnesium (Mg), calcium (Ca), and aluminum (Al), we can follow these steps:

### Step 1: Identify the number of valence electrons
- Magnesium (Mg) has 2 valence electrons.
- Calcium (Ca) also has 2 valence electrons.
- Aluminum (Al) has 3 valence electrons.

**Hint:** More valence electrons typically lead to stronger metallic bonds because they contribute more to the electron sea.
