Ionic Bonding Worksheet-1 - Name ______ Period - Studocu - Free Printable

You've uploaded an Ionic Bonding Worksheet that asks you to:

1. Draw atomic diagrams showing electrons in different energy levels.
2. Show electron transfer with arrows.
3. Draw the resulting ionic compound.
4. Fill out a table for each reaction, including:

🔹 Understanding Ionic Bonding

Ionic bonding occurs when one atom transfers electrons to another to achieve stable electron configurations (usually noble gas configuration). Metals lose electrons (form cations), nonmetals gain electrons (form anions).

We'll use Lewis dot structures and electron transfer diagrams to represent this.

## ✔ Reaction 1: Li + Cl → LiCl

- Li: Alkali metal, 1 valence electron → loses 1 e⁻ → becomes Li⁺
- Cl: Halogen, 7 valence electrons → gains 1 e⁻ → becomes Cl⁻

✔ Your answer is correct:
```
Li· + :Cl: → Li⁺ [:Cl:]⁻
```

| Atom | Valence e⁻ | Transfer | Ion |
|------|------------|----------|-----|
| Li | 1 | 1 transferred | Li⁺ |
| Cl | 7 | 1 gained | Cl⁻ |

✔️ Correct.

## ✔ Reaction 2: Ca + O → CaO

- Ca: Alkaline earth metal, 2 valence e⁻ → loses 2 e⁻ → Ca²⁺
- O: Oxygen, 6 valence e⁻ → gains 2 e⁻ → O²⁻

Your diagram shows:
```
Ca + ·Ö· → Ca²⁺ [∶Ö∶]²⁻
```
That's good.

| Atom | Valence e⁻ | Transfer | Ion |
|------|------------|----------|-----|
| Ca | 2 | 2 transferred | Ca²⁺ |
| O | 6 | 2 gained | O²⁻ |

✔️ Correct.

## ✔ Reaction 3: Be + F₂ → BeF₂

Note: The reaction should be Be + 2F → BeF₂, since fluorine exists as F₂ molecule, but we're focusing on atoms here.

- Be: 2 valence e⁻ → loses both → Be²⁺
- F: 7 valence e⁻ → each gains 1 e⁻ → F⁻

So, Be gives 1 e⁻ to each of two F atoms.

Your diagram:
```
Be + 2:F: → Be²⁺ [∶F∶]⁻ [∶F∶]⁻
```
This is correct.

| Atom | Valence e⁻ | Transfer | Ion |
|------|------------|----------|-----|
| Be | 2 | 2 transferred | Be²⁺ |
| F | 7 | each gains 1e⁻ | F⁻ |

✔️ Correct.

---

## ✔ Reaction 4: Mg + S → MgS

- Mg: 2 valence e⁻ → loses 2 → Mg²⁺
- S: 6 valence e⁻ → gains 2 → S²⁻

Diagram:
```
Mg + ·S· → Mg²⁺ [:S:]²⁻
```
Correct.

| Atom | Valence e⁻ | Transfer | Ion |
|------|------------|----------|-----|
| Mg | 2 | 2 transferred | Mg²⁺ |
| S | 6 | 2 gained | S²⁻ |

✔️ Correct.

---

## ✔ Reaction 5: K + F → KF

- K: 1 valence e⁻ → loses 1 → K⁺
- F: 7 valence e⁻ → gains 1 → F⁻

Diagram:
```
K· + :F: → K⁺ [:F:]⁻
```
Perfect.

| Atom | Valence e⁻ | Transfer | Ion |
|------|------------|----------|-----|
| K | 1 | 1 transferred | K⁺ |
| F | 7 | 1 gained | F⁻ |

✔️ Correct.

📌 Summary: All Answers Are Correct!

Your work is excellent — all Lewis structures, electron transfers, and ion charges are accurate.

However, to complete the worksheet fully, you should also draw atomic diagrams showing electron shells (like the sample for Li + F) for each reaction.

Here’s how to do it properly:

---

🔧 How to Draw Atomic Diagrams (Example: Li + F)

For Li:
- Nucleus: Li
- First shell: 2 electrons
- Second shell: 1 electron

For F:
- Nucleus: F
- First shell: 2 electrons
- Second shell: 7 electrons

Then draw an arrow from Li's outer electron to F's outer shell.

After bond:
- Li has only 2 electrons (like He)
- F now has 8 electrons (like Ne)

Same logic applies to others.

✔ Final Check: Table Completion

All entries in your table are correct:

| Reaction | Atoms | Valence e⁻ | Transfer | Ions Formed |
|--------|-------|------------|----------|-------------|
| 1) Li + Cl → LiCl | Li: 1, Cl: 7 | Li: 1 transfer, Cl: 1 gain | Li⁺, Cl⁻ |
| 2) Ca + O → CaO | Ca: 2, O: 6 | Ca: 2 transfer, O: 2 gain | Ca²⁺, O²⁻ |
| 3) Be + F → BeF₂ | Be: 2, F: 7 | Be: 2 transfer, F: each gains 1 | Be²⁺, F⁻ |
| 4) Mg + S → MgS | Mg: 2, S: 6 | Mg: 2 transfer, S: 2 gain | Mg²⁺, S²⁻ |
| 5) K + F → KF | K: 1, F: 7 | K: 1 transfer, F: 1 gain | K⁺, F⁻ |

✔ Everything matches chemical principles.
