Sulfur exists as molecules and argon exists as separate atoms. Compare the melting points and electrical conductivities of sulfur and argon, and explain your answers in terms of the structure and bonding of the two elements.

The Periodic Table: chemical periodicity: compare question
How this question is marked
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Compare means: Give similarities or differences between two things, and say which side each point belongs to. Write each point as a pair, for example: A is X, whereas B is Y. Two separate descriptions rarely earn the marks.
