Answer
Here are six common nonsilicate mineral groups along with the key ions or elements that define each group:
1. Carbonates:
Key ions: Carbonate ion (CO₃²⁻)
Example: Calcite (CaCO₃)
2. Sulfates:
Key ions: Sulfate ion (SO₄²⁻)
Example: Gypsum (CaSO₄·2H₂O)
3. Oxides:
Key elements: Oxygen (O) combined with various metallic elements
Example: Hematite (Fe₂O₃)
4. Halides:
Key ions: Halide ions such as chloride (Cl⁻), fluoride (F⁻), bromide (Br⁻), or iodide (I⁻)
Example: Halite (NaCl)
5. Sulfides:
Key elements: Sulfur (S) combined with various metallic elements
Example: Galena (PbS)
6. Native Elements:
Key elements: Minerals consisting of a single element
Example: Gold (Au), Silver (Ag), Diamond (C)
These mineral groups are distinguished by their unique chemical compositions and the presence of specific ions or elements. It's important to note that this list represents only a selection of nonsilicate mineral groups, and there are several other groups with different defining ions or elements.
