Ionic bonding Part 2

October 08, 2025

We are learning to:
a) know what is meant by the term ionic bond
b) be able to draw a diagram that shows the formation of ionic bonds
c) understand why table salt understand why table salt looks like crystals.

How do you feel today?

😒🙁😐🙂😃

Recall

ionic bonding

We are learning to:

a) know what is meant by the term ionic bond

b) be able to draw a diagram that shows the formation of ionic bonds

c) understand why table salt understand why table salt looks like crystals.

Metals form positive ions, and non-metals form negative ions. The ____________ of electrons from metal to non-metal atoms results in the formation of oppositely charged ions.

1. sharing
2. lost
3. transfer
4. gain

There is a strong ________________ attraction between oppositely-charged ions – this is the origin of the ionic bond which holds the ions together.

1. electrostatic
2. magnetic
3. electric
4. electromagnetic

A(n) ___________ is a diagram drawn to represent

the bonding in a molecule, or the electrons in an ion

1. Bohr's atomic model
2. dot-and-cross diagram
3. ionic diagram
4. equation

Any questions?

Chemical Structures

In substances that have ionic bonding, the ions are arranged in geometric 3D patterns that extend “forever,” called _________________.

1. Giant ionic structure
2. Giant ionic lattice
3. Giant metallic structure
4. Giant covalent structure

Giant Ionic Structure or Lattice

The electrostatic attraction of each ion

affects all the other ions around it. It

acts _____________in all directions.

1. differently
2. equally
3. neutrally
4. enormously

Giant Ionic Structure or Lattice of Sodium chloride (NaCl)

The giant lattice structure of ionic compounds shows a regular arrangement of __________________ positive and negative ions.

1. alternating
2. repeating
3. skipping
4. strong

Properties of substances with giant ionic structures

The regular arrangement of ions in the lattice gives these substances their _________________

structure and shape.

1. rigid
2. repeating
3. crystalline
4. strong

The Crystalline Structure of Giant Ionic Lattices

Any questions?

Ionic crystals are_______________ because once a layer of ions in the crystal has been forced to move, ions of the same charge will be next to each other, and they will repel, splitting the crystal.

1. rigid
2. brittle
3. crystalline
4. hard

Properties of substances with giant ionic structures

The Brittleness of 

Giant Ionic Lattices

Any questions?

In order to conduct electricity, there must be charge carriers (charged particles) which are free to move. In an ionic compound, these charged particles are the __________.

1. atoms
2. ions
3. cations
4. anions

Properties of substances with giant ionic structures

Solid ionic compounds conduct electricity.

1. TRUE
2. FALSE

Molten ionic compounds can conduct electricity. Why?

Any questions?

Melting or boiling requires the lattice to be broken down so the ions can move around. Throughout the lattice, the ionic bonds are very strong; it takes a lot of (heat) energy to

break the lattice apart so that the ions cannot move.

1. TRUE
2. FALSE

Today, we learned that:

• There are 4 types of chemical structures: Giant ionic structure or lattice, Giant Covalent Structure, Simple Molecules, and Giant Metallic structure.
• All ionic compounds have giant ionic structures.
• Ionic compounds are hard, brittle and crystalline.
• Ionic compounds have high boiling and melting points.
• The lattice of the ionic bonds is very strong; it takes a lot of energy to break the lattice apart so that the ions are free to move.
