Which phrase describes the composition of the most abundant mineral compounds on Earth?

carbonates, oxygen, and one or more organic compounds

oxygen, sulfates, and one or more nonmetals

oxalates, oxygen, and one or more organic compounds

Silicon, oxygen and one or more metals

Answer: Silicon, oxygen and one or more metals

Silicon, oxygen and one or more metals

Explanation:

Most abundant (mass percent) mineral compounds in the earth crust are:

Silicon dioxide (SiO₂) with a abundance of 42.86%

Magnesium oxide (MgO) with a abundance of 35.07%

Ferrous oxide (FeO) with a abundance of 8.97%

Aluminum oxide (Al₂O₃) with a abundance of 6.99%

So, as you can see the silicon and the oxygen (in the form of oxides) are the most the most common elements found in earth crust, followed by other metal compounds.
