GCSE Chemistry Revision "Limitations of Bonding Diagrams"

What is one advantage of using dot and cross diagrams to represent molecules?

They clearly show where the electrons are coming from by using dots for one atom's electrons and crosses for another's.

What limitation do dot and cross diagrams have?

They do not show the shape of the molecule.

What is a key disadvantage of two-dimensional stick diagrams?

They cannot indicate which electron in the covalent bond came from which atom, and they do not represent outer electrons not involved in bonds.

What does a three-dimensional stick diagram illustrate about a molecule?

It shows the shape of the molecule.

What is one advantage of using ball and stick diagrams for giant ionic lattices?

They provide a clear representation of the ions in three dimensions.

What is a major limitation of ball and stick diagrams regarding ion spacing?

They depict ions as widely spaced, whereas in reality, ions are packed closely together.

What benefit do space-filling diagrams offer?

They show how closely packed the ions are within the lattice.

What is a limitation of space-filling diagrams?

They make it difficult to visualize the three-dimensional packing of ions.

What common issue do both ball and stick and space-filling diagrams share?

They only show a tiny part of the giant crystal lattice, giving an impression that the structures are smaller than they actually are.
