C2.2.4 - Ionic compounds

Question 1

How do ionic compounds form?

Answer 1

When a metal reacts with a non-metal electrons are transferred from the metals to non-metals making positive and negative ions

Question 2

What is an ionic compound?

Answer 2

A compound containing oppositely charged ions from different elements

Question 3

What is the structure and bonding in ionic compounds?

Answer 3

In solid state it is arranged in a regular way. This is called a giant ionic lattice. The ions are held in place by strong electrostatic forces of attraction between oppositely charged ions

Question 4

What are ionic bonds?

Answer 4

Strong electrostatic force of attraction between oppositely charged ions

Question 5

What is a space-filling model?

Answer 5

A representation of ionic compounds and molecules in which balls represent the atoms or ions

Question 6

What is giant-ionic lattice?

Answer 6

A structure of ionic compounds in which oppositely charged particles are held in regular and repeating arrangement by strong electrostatic forces of attraction

Question 7

What is a ball-and-stick-model?

Answer 7

A representation of ionic compounds and molecules in which balls represent the atoms or ions, and springs or plastic links represent chemical bonds
