Why is calcium a metal? Why does it seem to have so few
The Ca 0 metal is not found often in nature for this reason. The "calcium" we talk about when we think of calcium scale on pluing is calcium carbonate, and other calcium salts. The oxidized calcium ion, Ca 2+ forms with carbonate, CO3 2-and forms an insoluble scale. The comparison here is the same as the difference between iron and rust.
