Calcium is not an alkali metal.
Translate from английский to испанский

Milk is a good source of calcium.

The famous white-sand beaches of Hawaii, for example, actually come from the poop of parrotfish. The fish bite and scrape algae off of rocks and dead corals with their parrot-like beaks, grind up the inedible calcium-carbonate reef material (made mostly of coral skeletons) in their guts, and then excrete it as sand.

Most structures that we call "coral" are, in fact, made up of hundreds to thousands of tiny coral creatures called polyps. Each soft-bodied polyp—most no thicker than a nickel—secretes a hard outer skeleton of limestone (calcium carbonate) that attaches either to rock or the dead skeletons of other polyps.

Decreases in carbonate ions can make building and maintaining shells and other calcium carbonate structures difficult for calcifying organisms such as oysters, clams, sea urchins, shallow water corals, deep sea corals, and calcareous plankton.

Alveolar bone has a high mineral content, mainly calcium and phosphate.
Translate from английский to испанский

Calcium, heated with a Bunsen burner, turns the flame orange-red.

Davy, a British chemist, isolated the pure elements barium, boron, calcium, magnesium, potassium, sodium and strontium, but we owe the discovery of metallic aluminium to Ørsted, a Danish physicist.

This element, considered to be radioactive and classified as a metal, is artificially produced by bombarding atoms of americium-243—an isotope of the element Americium (Am)—with ions of a rare isotope calcium-48 using a device called a cyclotron.

Parrotfish bite and scrape algae off of rocks and dead corals with their parrot-like beaks; grind the inedible calcium carbonate (reef material made mostly of coral skeletons) which is excreted as sand back onto the reef.
Translate from английский to испанский

The scientists used different kinds of atoms in their experiments. The American team used laser beams to teleport the properties of an atom of beryllium, a kind of metal. The team in Austria used a calcium atom. All the atoms were ions. This means they had an electric charge.

Over time, that calcium carbonate forms tall, rocky seamounts around the methane vents. Victoria Orphan suspected that these rocky areas served as a shelter for sea life. So she found a submersible — a small vehicle like a submarine — and went down 800 meters to the sea floor to prove it.

Scientists wanted to see how these developing larvae were being affected by the increased acidity of the ocean water caused by excess carbon dioxide in the atmosphere. Whitman Miller — an environmental scientist and ecologist with the Smithsonian research center — says oceans normally absorb about half of the carbon dioxide that's produced by living creatures. But when excess CO₂ is pumped into the atmosphere and dissolves into seawater, that contributes to an acidification, or a lowering of the pH of the oceans. A byproduct of that process — carbonic acid — rapidly converts to carbonate and bicarbonate ions, which Miller says are corrosive to the calcium carbonate shells of oysters and other marine species.

Oxalic acid, or "oxalate," is a naturally occurring plant chemical which, in the human diet, can react with calcium, iron, and other minerals to inhibit mineral absorption. Foods such as tea, beets, rhubarb, strawberries, spinach, and chocolate are known to increase oxalate in the urine and may contribute to kidney stone formation.

Dry fruits and vegetables are rich in calcium.

Calcium is an essential mineral for the human body.

With osteoporosis, there isn't much calcium in the bones.

On the positive side, men who did not develop colon cancer had fiber-rich diets and ate foods containing a lot of calcium and vitamin D.
