What is the ratio of sodium to chloride particles?

1. 1:1
2. 1:2
3. 2:2
4. 1000:1000

• What is the chemical formula based on this ratio?

Question & A

Making a 3D Model

• Group work
• Make a 3D model of the lattice structure of sodium chloride using sticks and moulding clay in 5 MINUTES

• How do the particles stay together in reality?

Question & A

• What conclusion can you make for this diagram?

• "Opposite attracts."
• In an ionic lattice structure, "electrostatic force of attraction" keeps the particles together.

MAIN IDEA

• Sodium ion is a charged sodium atom. 

MAIN IDEA

• Chloride ion is a charged chlorine atom.
