Identify What two elements are found in all of the minerals in the figure? Explain your answer
The Minerals Are Quartz, Mica, And Feldspar
The two elements found in all of the minerals mentioned (quartz, mica, and feldspar) are oxygen (O) and silicon (Si).
Quartz, which has the chemical formula SiO2, consists of silicon (Si) and oxygen (O) atoms. It is composed of silicon and oxygen tetrahedra linked together.
Mica, which is a group of minerals, also contains oxygen (O) and silicon (Si). The basic structure of mica consists of sheets of aluminum (Al) or magnesium (Mg) hydroxide, which are sandwiched between layers of silicon-oxygen (Si-O) tetrahedra.
Feldspar, another group of minerals, contains oxygen (O) and silicon (Si) as well. The composition of feldspar varies, but it generally consists of aluminum (Al), silicon (Si), and oxygen (O) atoms, with additional elements such as potassium (K), sodium (Na), or calcium (Ca) in some varieties.
Therefore, the common elements found in all of these minerals are oxygen (O) and silicon (Si).
