Periodic Table Database | Chemogenesis

Hinrichs'' system is based on the relationship of what he called: "pantogens, with its atoms called panatoms, which explains the numerical relations of atomic weights and gives a simple classifiion of the elements." This classifiion system culminated in 1867 in his spiral periodic table, which better clarified the groupings of elements.

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.
