Question

diamond and graphite contain only carbon atoms, yet they are very different objects with very different properties. why are diamond and graphite different?
a. their atoms are arranged differently.

b. they contain different atoms.

c. their subatomic particles are different.

d. they contain different elements.

Explanation:

Diamond and graphite are allotropes of carbon, meaning they are made of the same carbon atoms (so B and D are wrong) and have the same subatomic particles (so C is wrong). The difference in their properties comes from the different arrangements of carbon atoms in their structures. Diamond has a tetrahedral lattice structure, while graphite has a layered hexagonal structure.

Answer:

A. Their atoms are arranged differently.
