Ionic Bonding Basics
📚 Part 1: Understanding Ions and Ionic Bonding
1. What is an ion?
An atom that has gained or lost electrons
An atom that shares electrons with another atom
A neutral atom with equal protons and electrons
A molecule made of two or more atoms
2. Which type of elements typically form ionic bonds?
Two metals
Two non-metals
A metal and a non-metal
Noble gases only
3. Complete the sentence: In ionic bonding, electrons are _____________ from one atom to another.
Answer: _____________________
4. What is the difference between a cation and an anion?
5. Using the example of sodium chloride (NaCl), explain how an ionic bond forms between sodium and chlorine atoms.
⚡ Part 2: Properties of Ionic Compounds
6. Which of the following are properties of ionic compounds? (Select all that apply)
High melting and boiling points
Conduct electricity when solid
Often soluble in water
Conduct electricity when molten or dissolved
Form crystal lattice structures
7. Explain why ionic compounds have high melting points.
8. Why do ionic compounds conduct electricity when dissolved in water but not when solid?
9. Give two real-life examples of ionic compounds and state one use for each.
Example 1: _________________ Use: _________________________________
Example 2: _________________ Use: _________________________________
🔬 Part 3: Applying Your Knowledge
10. Create a flowchart showing the steps of ionic bond formation. Use the space below to draw your flowchart with arrows and labels.
11. Compare ionic bonding to covalent bonding by completing the table below:
| Feature | Ionic Bonding | Covalent Bonding |
|---|---|---|
| What happens to electrons? | ||
| Types of elements involved | ||
| Electrical conductivity |
Extension Activity: Research and explain why table salt (NaCl) dissolves easily in water but oil does not. What does this tell us about the nature of ionic compounds?
