🔬 Objective of the Worksheet

For each pair of elements:
1. Draw atomic diagrams showing electron configuration (energy levels).
2. Show electron transfer with arrows.
3. Draw the resulting ions and compound.
4. Fill in a table with:
- Valence electrons
- Electron transfer direction
- Ions formed

This illustrates ionic bonding, where metals lose electrons to form cations and nonmetals gain electrons to form anions.

## ✔ Solutions Explained

1) Li + Cl → LiCl

- Li (Lithium): Metal, 1 valence electron.
- Cl (Chlorine): Nonmetal, 7 valence electrons.
- Electron Transfer: Li donates 1 electron to Cl.
- Resulting Ions:
- Li⁺ (loses 1e⁻)
- Cl⁻ (gains 1e⁻)
- Compound: LiCl (1:1 ratio)

✔ Correctly shown in the diagram and table.

2) Ca + O → CaO

- Ca (Calcium): Metal, 2 valence electrons.
- O (Oxygen): Nonmetal, 6 valence electrons.
- Electron Transfer: Ca donates 2 electrons; O accepts 2 electrons.
- Resulting Ions:
- Ca²⁺
- O²⁻
- Compound: CaO (1:1 ratio)

✔ Correct — both atoms achieve stable octets.

3) Be + F₂ → BeF₂

- Be (Beryllium): Metal, 2 valence electrons.
- F (Fluorine): Nonmetal, 7 valence electrons.
- Electron Transfer: Be donates 2 electrons (1 to each F atom).
- Each F gains 1 electron → becomes F⁻.
- Resulting Ions:
- Be²⁺
- Two F⁻ ions
- Compound: BeF₂ (1:2 ratio)

✔ Correct — Be loses 2e⁻, two F atoms each gain 1e⁻.

4) Mg + S → MgS

- Mg (Magnesium): Metal, 2 valence electrons.
- S (Sulfur): Nonmetal, 6 valence electrons.
- Electron Transfer: Mg donates 2 electrons; S accepts 2 electrons.
- Resulting Ions:
- Mg²⁺
- S²⁻
- Compound: MgS (1:1 ratio)

✔ Correct — both achieve noble gas configurations.

5) K + F → KF

- K (Potassium): Metal, 1 valence electron.
- F (Fluorine): Nonmetal, 7 valence electrons.
- Electron Transfer: K donates 1 electron to F.
- Resulting Ions:
- K⁺
- F⁻
- Compound: KF (1:1 ratio)

✔ Correct — similar to LiF.

| 4) Mg + S → MgS | Mg | 2 | Donates 2e⁻ | Mg²⁺ |
| | S | 6 | Accepts 2e⁻ | S²⁻ |
| 5) K + F → KF | K | 1 | Donates 1e⁻ | K⁺ |
| | F | 7 | Accepts 1e⁻ | F⁻ |

## 💡 Key Concepts Illustrated:

1. Metals (Li, Na, K, Ca, Mg, Be) tend to lose electrons to form cations.
2. Nonmetals (F, Cl, O, S) tend to gain electrons to form anions.
3. The number of electrons lost = number gained → charge balance.
4. Resulting compound has neutral overall charge.
5. Octet Rule: Atoms gain/lose electrons to have 8 valence electrons (except H, He, or Be).

## ✔ Conclusion

All answers on the worksheet are correct and well-explained:
- Electron transfers are accurately shown with arrows.
- Lewis dot structures reflect valence electrons.
- Ion charges match expected values.
- Final compounds are correctly formed.

This worksheet effectively teaches ionic bonding using real examples from the periodic table.
