Ionic bonding worksheet with electron dot structures and compound naming exercises.

Absolutely! Let’s solve this Type 1 (Ionic) Bonding Worksheet step by step. The goal is to:

1. Draw electron dot structures (Lewis dot diagrams) for each atom before and after the reaction.
2. Use arrows to show electron transfer.
3. Name the ionic compound formed.
4. Fill in the table with:
- Atom symbol
- Number of valence electrons
- Electron transfer (who loses/gains how many)
- Ion formed

---

We’ll go row by row, following the sample given (Li + F → LiF).

## ✔ 3) Be + F → BeF₂

Name the ionic compound: Beryllium fluoride

#### 🔬 Electron Dot Structures & Transfer:

- Beryllium (Be) – Group 2 → 2 valence electrons
- Loses 2 electrons to achieve noble gas configuration (like He).
- Forms Be²⁺

- Fluorine (F) – Group 17 → 7 valence electrons
- Each F atom gains 1 electron to complete octet.
- Since there are two F atoms in BeF₂, each F gains 1 electron → forms F⁻

> 🔄 So: Be transfers one electron to each of two F atoms.

#### 🖍️ Drawing (Text Description):

```
Before Reaction:

Be : (2 dots — one on each side, or just two dots)

F : (7 dots — 3 pairs + 1 single)

F : (same as above)

After Reaction:

Be²⁺ (no dots — lost both electrons)

[ F : ]⁻ (8 dots — complete octet)

[ F : ]⁻ (8 dots — complete octet)
```

→ Arrow from Be to each F showing electron transfer.

#### 📊 Table Entry:

| Atoms | Valence electrons | Electron transfer from/to each atom | Ions formed in the product |
|-------|-------------------|-------------------------------------|----------------------------|
| Be | 2 | Be loses 2 e⁻ | Be²⁺ |
| F | 7 | Each F gains 1 e⁻ | F⁻ |

> ⚠️ Note: There are two F atoms, so total 2 electrons transferred from Be to two F atoms (1 each). But since the table says “from/to each atom”, we write per atom.

## ✔ 3) Mg + S → MgS
*(Note: This is listed as “3)” again — probably a typo; should be #4 or #5. We’ll treat it as next item.)*

Name the ionic compound: Magnesium sulfide

#### 🔬 Electron Dot Structures & Transfer:

- Magnesium (Mg) – Group 2 → 2 valence electrons
- Loses 2 electrons → becomes Mg²⁺

- Sulfur (S) – Group 16 → 6 valence electrons
- Gains 2 electrons → completes octet → becomes S²⁻

> 🔄 So: Mg transfers both electrons to S.

#### 🖍️ Drawing (Text Description):

```
Before:

Mg : (2 dots)

S : (6 dots — 3 pairs)

After:

Mg²⁺ (no dots)

[ S : ]²⁻ (8 dots — complete octet)
```

→ Arrow from Mg to S showing 2 electrons transferred.

#### 📊 Table Entry:

| Atoms | Valence electrons | Electron transfer from/to each atom | Ions formed in the product |
|-------|-------------------|-------------------------------------|----------------------------|
| Mg | 2 | Mg loses 2 e⁻ | Mg²⁺ |
| S | 6 | S gains 2 e⁻ | S²⁻ |

## ✔ 4) K + F → KF

Name the ionic compound: Potassium fluoride

#### 🔬 Electron Dot Structures & Transfer:

- Potassium (K) – Group 1 → 1 valence electron
- Loses 1 electron → becomes K⁺

- Fluorine (F) – Group 17 → 7 valence electrons
- Gains 1 electron → becomes F⁻

> 🔄 So: K transfers its 1 electron to F.

#### 🖍️ Drawing (Text Description):

```
Before:

K . (1 dot)

F : (7 dots)

After:

K⁺ (no dots)

[ F : ]⁻ (8 dots — complete octet)
```

→ Arrow from K to F showing 1 electron transferred.

#### 📊 Table Entry:

| Atoms | Valence electrons | Electron transfer from/to each atom | Ions formed in the product |
|-------|-------------------|-------------------------------------|----------------------------|
| K | 1 | K loses 1 e⁻ | K⁺ |
| F | 7 | F gains 1 e⁻ | F⁻ |

## ✔ Final Answer Summary:

For 3) Be + F → BeF₂

Name: Beryllium fluoride
Table:

| Atoms | Valence electrons | Electron transfer from/to each atom | Ions formed in the product |
|-------|-------------------|-------------------------------------|----------------------------|
| Be | 2 | Be loses 2 e⁻ | Be²⁺ |
| F | 7 | F gains 1 e⁻ | F⁻ |

> (Note: Two F atoms needed → total 2 e⁻ gained, but per atom it’s 1 e⁻.)

For 3) Mg + S → MgS *(Assuming this is meant to be #4)*

Name: Magnesium sulfide
Table:

| Atoms | Valence electrons | Electron transfer from/to each atom | Ions formed in the product |
|-------|-------------------|-------------------------------------|----------------------------|
| Mg | 2 | Mg loses 2 e⁻ | Mg²⁺ |
| S | 6 | S gains 2 e⁻ | S²⁻ |

For 4) K + F → KF

Name: Potassium fluoride
Table:

| Atoms | Valence electrons | Electron transfer from/to each atom | Ions formed in the product |
|-------|-------------------|-------------------------------------|----------------------------|
| K | 1 | K loses 1 e⁻ | K⁺ |
| F | 7 | F gains 1 e⁻ | F⁻ |

## 💡 Pro Tip for Drawing:

- Always draw valence electrons as dots around the element symbol.
- Metals (left side of periodic table) lose electrons → become cations (+).
- Nonmetals (right side) gain electrons → become anions (-).
- Arrows point from metal to nonmetal showing electron flow.
- Final ions should have complete outer shells (usually 8, except H/He).
