Calcite: Mineral information, data and localities.

Calcite Group. Calcite-Rhodochrosite Series. A very common and widespread mineral with highly variable forms and colours. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhoohedral cleavage in most varieties.

Mineral | Article about mineral by The Free Dictionary

The development of mineral crystals and crystal aggregates through all the given stages was unified under the general term “mineral ontogenesis” by the Soviet scientist D. P. Grigor’ev in 1961. A mineral can be formed from media of varying phase states (melt, solution, gas) in a suspension or on a substrate.

Valence (chemistry) - Howling Pixel

Valence (chemistry) In chemistry, the valence or valency of an element is a measure of its coining power with other atoms when it forms chemical compounds or molecules.The concept of valence developed in the second half of the 19th century and helped successfully explain the molecular structure of inorganic and organic compounds. The quest for the underlying causes of valence led to the

Period 5 element - WikiVisually

A period 5 element is one of the chemical elements in the fifth row (or period) of the periodic table of the elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic nuer increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements with similar behaviour fall into the

Barium - Howling Pixel

Barium. Barium is a chemical element with syol Ba and atomic nuer 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal.Because of its high chemical reactivity, barium is never found in nature as a free element.Its hydroxide, known in pre-modern times as baryta, does not occur as a mineral, but can be prepared by heating barium carbonate.
