submit
part b complete previous part(s)
part c complete previous part(s)
part d complete previous part(s)

Explanation:

To solve this, we use the prefixes in chemical nomenclature:

• Mono- = 1, Di- = 2, Tri- = 3, Tetra- = 4, Penta- = 5, Hexa- = 6.

Step 1: Identify prefixes and atom counts

• monochloride: prefix mono- → 1 atom.
• difluoride, dibromide: prefix di- → 2 atoms.
• trifluoride, trioxide: prefix tri- → 3 atoms.
• tetrasulfide, tetrabromide: prefix tetra- → 4 atoms.
• pentachloride: prefix penta- → 5 atoms.
• hexabromide: prefix hexa- → 6 atoms.

Answer:

• 1 atom: monochloride
• 2 atoms: difluoride, dibromide
• 3 atoms: trifluoride, trioxide
• 4 atoms: tetrasulfide, tetrabromide
• 5 atoms: pentachloride
• 6 atoms: hexabromide
