different ores and their chemical formulas

Chemical Formula - Definition, Types and Examples - Biology Dictionary

A chemical formula is a notation used by scientists to show the number and type of atoms present in a molecule, using the atomic symbols and numerical subscripts. A chemical formula is a simple representation, in writing, of a three dimensional molecule that exists. A chemical formula describes a substance, down to the exact atoms which make it up.

Adamantane. This molecule always brings a smile to the lips of undergrads when they first hear its name, especially in the UK. For those not in the know, Adam Ant was an English pop star in the early 1980's famous for silly songs and strange make-up. Adamantane actually gets its name from the Greek adamas meaning 'indestructible', since it's the chemical building block of diamond.

Coordination Compounds - GitHub Pages

Although the chemical composition of such compounds was readily established by existing analytical methods, their chemical nature was puzzling and highly controversial. The major problem was that what we now call valence (i.e., the oxidation state) and coordination number were thought to be identical. As a result, highly implausible (to modern eyes at least) structures were proposed for such ...

Hydroxides are compounds of a metallic element and water or the hydroxyl anion (OH)-. The oxide minerals tend to be relatively hard, and some of them may be used as gemstones. Many provide economically important metal ores. Minerals of the hydroxide class tend to be softer and less dense than oxides.

Identifying Minerals | Geology | | Course Hero

Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2-.

mineral - Classification of minerals | Britannica

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 of mineral classification.
