Draw Lewis dot symbols for the following elements :
`{:("(i) Magnesium","(ii) Phosphorus"),("(iii) Chlorine","(iv) Boron"),("(v) Xenon","(vi) Silicon"):}`

Explanation

To draw the Lewis dot symbols for the given elements, we need to determine the number of valence electrons for each element based on its group in the periodic table. Here’s a step-by-step solution for each element:

### Step-by-Step Solution:

1. **Magnesium (Mg)**:
- **Group**: 2
- **Valence Electrons**: 2
- **Lewis Dot Symbol**: Place two dots around the symbol for magnesium (Mg).
