Elements:
each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number, i.e., the number of protons in the nuclei of its atoms.
Sulfides:
a binary compound of sulfur with another element or group.
Halides:
a binary compound of a halogen with another element or group.
Oxides:
a binary compound of oxygen with another element or group.
Carbonates:
a salt of the anion CO32–, typically formed by reaction of carbon dioxide with bases.
Borates:
The borate minerals are minerals which contain a borate anion group. The borate (BO3) units may be polymerized similar to the SiO4 unit of the silicate mineral class. 
Sulfates:
a salt or ester of sulfuric acid, containing the anion SO42− or the divalent group —OSO2O—.
Phosphates:
a salt or ester of sulfuric acid, containing the anion SO42− or the divalent group —OSO2O—.
Silicates:
any of the many minerals consisting primarily of SiO42− combined with metal ions, forming a major component of the rocks of the earth's crust.
Organic Compounds:
An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon. Carbonates, simple oxides of carbon, and cyanide molecules do have carbon, but they are not regarded as organic.
