The Mohs Scale of Hardness for Metals: Why It Is Important
Where a metal stands on the Mohs scale indies which other metals can scratch it. For example, gold’s hardness rating is 2.5-3, which is lower than that of most other metals. To use an example, one of the hardest substances on earth, diamond, is rated 10 on the Mohs scale, while plastic and pencil lead, for instance, are on the other end of the scale, with a hardness grade of 1.
The calcium myth - Better Bones
Calcium ascorbate and calcium carbonate are generally not as easily absorbed as the citrate forms if stomach HCl is low. However, they are absorbed quite readily when taken with food. Generally speaking, all types of calcium are absorbed more easily if taken with meals — no matter what form you choose.

Calcium ion | Ca+2 - PubChem
Calcium is essential for living organisms, particularly in cell physiology, and is the most common metal in many animals. Physiologically, it exists as an ion in the body. Calcium coines with phosphorus to form calcium phosphate in the bones and teeth.
Calcium in Plants
Calcium is an essential plant nutrient. It is required for various structural roles in the cell wall and meranes, it is a counter‐ion for inorganic and organic anions in the vacuole, and the cytosolic Ca 2+ concentration ([Ca 2+] cyt) is an obligate intracellular messenger coordinating responses to numerous developmental cues and environmental challenges.
