mixture:
diagrams: left (mixture: no) has a molecule with 3 atoms (2 black, 1 zigzag-patterned); below, another same 3-atom molecule and a 2-atom molecule (zigzag + dotted). right (mixture: yes) has four 2-atom molecules: two (zigzag + dotted), two (striped + striped), and another (zigzag + dotted), (striped + striped)?

Explanation:

To solve the problem of identifying compounds and mixtures, we analyze the left and right sections:

Left Section (Mixture: NO)

• Atoms: 3 (one zig - zag, two black).
• Elements: 2 (zig - zag and black are different elements).
• Molecules: 1 (only one type of molecule here).
• Compounds: 1 (a molecule made of different elements, so it's a compound).
• Mixture: NO (only one type of molecule, so it's a pure substance, a compound).

Right Section (Mixture: YES)

• Atoms: 8 (let's count: for the zig - zag - dotted molecules, each has 2 atoms, and there are 2 of them; for the striped - striped molecules, each has 2 atoms, and there are 2 of them. So (2×2)+(2×2) = 8).
• Elements: 3 (zig - zag, dotted, striped are different elements).
• Molecules: 4 (2 zig - zag - dotted molecules and 2 striped - striped molecules).
• Compounds: 2 (the zig - zag - dotted molecules are compounds as they have different elements; the striped - striped molecules are elements, not compounds).
• Mixture: YES (there are two different types of molecules: the compound molecules (zig - zag - dotted) and the element molecules (striped - striped), so it's a mixture of a compound and an element).

Final Answers (Filling the Table)

	Left (Mixture: NO)	Right (Mixture: YES)
Elements	2	3
Molecules	1	4
Compounds	1	2
Mixture	NO	YES

If we consider the left section's compound: 1, right section's compound: 2, left mixture: NO, right mixture: YES.
