3.3 Ionic Bondig

Question 1

Define ionic bonding?

Answer 1

Attraction between oppositely charged ions

Question 2

Give all aspects of Ionic bonding?

Answer 2

held by a strong electrostatic force of attraction
High melting/boiling points
Don’t conduct electricity when a solid
Held together in a lattice pattern

Question 3

What’s the difference between an ion and an atom?

Answer 3

Atoms are uncharged
Ions are charged

Question 4

What’s the difference between Oxidisation and reduction?

Answer 4

Oxidisation = loss of electrons
Reduction = gain of electrons

Question 5

CaO

Question 7

Write the formula for Sodium Iodide?

Answer 7

NaI

Question 8

Which will conduct electricity and heat better a solid ionic compound or a molten/dissolved ionic compound? (Explain)

Answer 8

Solid –> Won’t as ions are stuck in place aren’t free to move
Molten/Dissolved –> Will as ions are free to move
