C2 : Limitations of bonding diagrams

Question 1

What are the limitations to dot and cross diagrams

Answer 1

They do not tell us about the shape of the molecule

Question 2

What are the limitations to stick diagrams

Answer 2

We cannot tell which electron in the covalent bond came from
Gives us no idea about electrons that are not in bonds
Do not give us accurate information on molecule shape

Question 3

What are the benefits to a 3-d stick diagram

Answer 3

Shows the shape of the molecule

Question 4

What are the benefits to the ball and stick diagram

Answer 4

We can see the ions in 3 dimensions

Question 5

What are the limitations to Ball and stick diagram

Answer 5

It shows the ions as widely spaced where in reality they are tightly packed

Question 6

What are the benefits to using a space filling diagram

Answer 6

Gives us an idea on how closely packed the ions are

Question 7

What are the limitations to using a ball and stick diagram

Answer 7

It is hard to see the 3 dimensional packing

Question 8

What are the limitations to with ball and stick and space filling diagrams

Answer 8

They only show a tiny part of the giant crystal lattice giving a mistaken interpretation about the sizes of these structures
