To solve the problem, we need to determine whether each item listed is a mineral or not. A mineral is defined by specific criteria:
1.
Natural: It must occur naturally.
2.
Inorganic: It must be inorganic (not produced by living organisms).
3.
Solid: It must be solid at room temperature.
4.
Crystalline: It must have a crystalline structure.
5.
Definite Chemical Composition: It must have a definite chemical composition.
Let's analyze each item step by step:
---
Mineral Column
-
Diamonds: Yes, diamonds are minerals. They are natural, inorganic, solid, crystalline, and have a definite chemical composition (pure carbon, C).
-
Gold: Yes, gold is a mineral. It is natural, inorganic, solid, and has a definite chemical composition (Au).
-
Quartz: Yes, quartz is a mineral. It is natural, inorganic, solid, crystalline, and has a definite chemical composition (silicon dioxide, SiO₂).
-
Topaz: Yes, topaz is a mineral. It is natural, inorganic, solid, crystalline, and has a definite chemical composition (aluminum fluorosilicate hydroxide).
---
Non-Mineral Column
-
Bone: No, bone is not a mineral. It is organic (produced by living organisms) and does not meet the inorganic criterion.
-
Coal: No, coal is not a mineral. It is organic (formed from decomposed plant material) and does not meet the inorganic criterion.
-
Fossil: No, fossils are not minerals. They are typically composed of organic remains that have been replaced by minerals over time but are not themselves minerals.
-
Granite: No, granite is not a mineral. It is a rock composed of multiple minerals (e.g., quartz, feldspar, mica), so it is not a single mineral.
-
Iceberg: No, icebergs are not minerals. While they are solid and natural, they do not have a definite chemical composition (they are primarily water, H₂O, which is not considered a mineral).
-
Pearl: No, pearls are not minerals. They are organic, formed by mollusks, and do not meet the inorganic criterion.
-
Rock Salt: No, rock salt is not a mineral. While it is natural and has a definite chemical composition (sodium chloride, NaCl), it is not crystalline in the way minerals are typically defined.
-
Talc: No, talc is not a mineral. While it is natural and has a definite chemical composition (magnesium silicate hydrate), it is not crystalline in the way minerals are typically defined.
-
Wood: No, wood is not a mineral. It is organic (produced by plants) and does not meet the inorganic criterion.

- Gold
- Quartz
- Topaz
####
Non-Mineral Column
- Bone
- Coal
- Fossil
- Granite
- Iceberg
- Pearl
- Rock Salt
- Talc
- Wood

Answer
The final sorted list is:
Mineral:
- Diamonds
- Gold
- Quartz
- Topaz
Non-Mineral:
- Bone
- Coal
- Fossil
- Granite
- Iceberg
- Pearl
- Rock Salt
- Talc
- Wood
$$
\boxed{
\text{Mineral: Diamonds, Gold, Quartz, Topaz}
}
$$
$$
\boxed{
\text{Non-Mineral: Bone, Coal, Fossil, Granite, Iceberg, Pearl, Rock Salt, Talc, Wood}
}
$$
