Question

: Four other pairs of elements in the same chemical family are listed below. List the number of valence electrons in each element. Beryllium _____ Magnesium _____ Nitrogen _____ Phosphorus _____ Oxygen _____ Sulfur _____ Fluorine _____ Chlorine _____

Answer 1

To determine the number of valence electrons for each of the elements listed, we can refer to their group number in the periodic table. Here are the valence electrons for each of the specified elements:

- **Beryllium (Be)**: 2 valence electrons (Group 2)
- **Magnesium (Mg)**: 2 valence electrons (Group 2)

- **Nitrogen (N)**: 5 valence electrons (Group 15)
- **Phosphorus (P)**: 5 valence electrons (Group 15)

- **Oxygen (O)**: 6 valence electrons (Group 16)
- **Sulfur (S)**: 6 valence electrons (Group 16)

- **Fluorine (F)**: 7 valence electrons (Group 17)
- **Chlorine (Cl)**: 7 valence electrons (Group 17)

Here's a summary:

- Beryllium (Be): 2 valence electrons
- Magnesium (Mg): 2 valence electrons
- Nitrogen (N): 5 valence electrons
- Phosphorus (P): 5 valence electrons
- Oxygen (O): 6 valence electrons
- Sulfur (S): 6 valence electrons
- Fluorine (F): 7 valence electrons
- Chlorine (Cl): 7 valence electrons
