2012-10-22 · If you have a pure piece of metal, you can control the size of the grains by heat treatment or by working the metal. Heating a metal tends to shake the atoms into a more regular arrangement - decreasing the nuer of grain boundaries, and so making the metal softer. Banging the metal around when it is cold tends to produce lots of small grains.

WebElements Periodic Table » Calcium » the essentials

Calcium is classified chemically as one of the alkaline earth elements (that is, in Group 2 of the periodic table. The metal is rather reactive. It readily forms a white coating of calcium nitride (Ca 3 N 2) in air. It reacts with water and the metal burns with a yellow-red flame, forming largely the nitride.

In medicine. The use of calcium preparations eliminates disturbances related to a deficiency of Ca 2 + ions in the body (for example, in tetanus, spasmophilia, and rickets). Calcium preparations reduce increased sensitivity to allergens and are used in the treatment of allergic conditions (serum allergy, nettle rash, angioneurotic edema, hay fever).

2019-4-20 · A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires).
