What Are Natural Monatomic Minerals?

Monatomic Minerals were discovered by David Hudson and scientists from the former Metallurgical Society of the Soviet Union in 1994. They are single-state atomic minerals that have not evolved into the complex atomic structure characteristic of metallic minerals. The electrons of a monatomic mineral exist in a high spin state.

Atomic Absorption Spectroscopy (AAS) Chemistry Tutorial

Atomic Absorption Spectroscopy (AAS) can be used to determine the lead concentration in soil collected from the side of a road. A student prepared standard lead solutions for comparison and the aborbance of each solution was measured. A road-side soil sample was also prepared. The results are shown in the table below.

Mineral

Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level Get price
