Question

which of the following models represent a molecule, but not a compound? a, b, and c a, d, and c b, e, and f all of the above

Explanation:

A molecule is formed when two or more atoms bond together. A compound is a molecule that contains at least two different elements.

• In option A: It is a molecule (two same - colored spheres, representing two same atoms). Since there is only one type of atom, it is not a compound.
• In option B: It is a compound (different - colored spheres, representing different atoms).
• In option C: It is a molecule (two same - colored spheres, representing two same atoms). Since there is only one type of atom, it is not a compound.
• In option D: It is a molecule (two same - colored spheres, representing two same atoms). Since there is only one type of atom, it is not a compound.
• In option E: It is a compound (different - colored spheres, representing different atoms).
• In option F: It is a compound (different - colored spheres, representing different atoms).

Answer:

A, D, and C
