10.4 INSIDE IONIC COMPOUNDS

Question 1

What is ionic bonding?

Answer 1

Oppositely charged ions are attracted to each other by strong electrostatic force

Question 2

What is ionic bonding formed between?

Answer 2

Metal atom and non-metal atom

Question 3

What does ionic bonding produce?

Answer 3

Ionic compound

Question 4

Why is chlorine ion a negative ion?

Answer 4

1. Protons have positive charge and electrons have negative charge
2. Chlorine ion have more electron than proton

Question 5

What is giant ionic structure?

Answer 5

Ionic bonding hold all the positive and negative ions in a 3D pattern

Question 6

What are the physical properties of ionic compounds?

Answer 6

1. High melting and boiling point
   - Contains large numbers of ions, a lot of energy needed to overcome this ionic bonding
2. Brittle
   - When you hit or drop an ionic crystal, the layers of ions shift.
   - This can cause ions with the same charge to line up next to each other (like positive next to positive).
   - Like charges repel, so the crystal shatters or breaks easily.
