Ionic Compounds

Question 1

What form of diagram is used to show ionic bonding

Answer 1

Dot and cross diagram

Question 2

What do dot and cross diagrams show about an atom or an ion?

Answer 2

Its arrangement of electrons

Question 3

How is an electron represented on a dot and cross diagram?

Answer 3

By a dot or a cross

Question 4

Describe one advantage and one disadvantage of using a dot and cross diagram.

Answer 4

They are useful for showing how ionic compounds are formed however they do not show the structure of the compound

Question 5

What kind of structure do ionic compounds have?

Answer 5

Giant ionic lattice structure

Question 6

Describe the bonding structure of ionic compounds

Answer 6

Ions in a closely packed regular lattice with very strong electrostatic forces of attraction between oppositely charged ions in all directions.

Question 7

State the properties of ionic compounds.

Answer 7

They have high melting and boiling points due to the strong forces of attraction between the ions, solid ionic compounds do not conduct electricity since the ions are fixed in place and cannot flow, and most ionic compounds easily dissolve in water

Question 8

What kind of model can you use to represent an ionic compound?

Answer 8

Space-filling
