What is the anionic group that occurs in carbonate minerals? Identify the elements that bond to this group and state the two most common carbonates that exists in minerals

Answer 1

The anionic group that occurs in carbonate minerals is the carbonate ion (CO₃²⁻).

The elements that typically bond to the carbonate group in carbonate minerals are generally metals, which can include common elements like calcium (Ca), magnesium (Mg), iron (Fe), and sodium (Na).

The two most common carbonates that exist in minerals are:

1. Calcite (CaCO₃) - a key component of sedimentary rocks and also found in limestone and marble.
2. Dolomite (CaMg(CO₃)₂) - composed of calcium and magnesium carbonates, commonly found in sedimentary rock formations.

These minerals are significant both geologically and industrially.
