1. Calcium

   Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin calx "lime", which was obtained from heating limestone. Some calcium compounds were known to the ancients, though their chemistry was unknown until the seventeenth century. Pure calcium was isolated in 1808 via electrolysis of its oxide by Humphry Davy, who named the element. Calcium compounds are widely used in many industries: in foods and pharmaceuticals for calcium supplementation, in the paper industry as bleaches, as components in cement and electrical insulators, and in the manufacture of soaps. On the other hand, the metal in pure form has few applications due to its high reactivity; still, in small quantities it is often used as an alloying component in steelmaking, and sometimes, as a calcium–lead alloy, in making automotive batteries. Calcium is the most abundant metal and the fifth-most abundant element in the human body. As electrolytes, calcium ions (Ca2+) play a vital role in the physiological and biochemical processes of organisms and cells: in signal transduction pathways where they act as a second messenger; in neurotransmitter release from neurons; in contraction of all muscle cell types; as cofactors in many enzymes; and in fertilization. Calcium ions outside cells are important for maintaining the potential difference across excitable cell membranes, protein synthesis, and bone formation.

1. calcium

   Calcium is a chemical element represented by the symbol Ca and atomic number 20. It is a silver-white, soft alkaline earth metal that is the fifth most abundant element by mass in the Earth's crust. It is also the third most abundant metal, after iron and aluminum. In its pure form, it is highly reactive and quickly forms a dull grey-white oxide and nitride coating when exposed to air. Calcium has various applications, such as forming alloys with different metals and as a reducing agent in the production of other metals. It is also necessary for the development of the human body, especially for bone structure and health.

1. Calcium

   Calcium is the chemical element with symbol Ca and atomic number 20. Calcium is a soft gray alkaline earth metal, and is the fifth-most-abundant element by mass in the Earth's crust. Calcium is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Calcium is essential for living organisms, in particular in cell physiology, where movement of the calcium ion Ca2+ into and out of the cytoplasm functions as a signal for many cellular processes. As a major material used in mineralization of bone, teeth and shells, calcium is the most abundant metal by mass in many animals.

1. Calcium

   A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

Examples of calcium in a Sentence

1. Brittany Verras:

   Carbohydrates provide the fuel and we store it for later use. We pull on that for endurance or really demanding periods like during sprinting, and then protein helps us build muscle and repair tissue, but as far as the vitamins and minerals, and this is true for all athletes, we need to be getting higher calcium, omega 3s and vitamin D.

2. Kristine Arthur:

   For general muscle aches, food containing magnesium or calcium may help ease soreness.

3. Jeff Wright:

   We've just found a way to make that a much faster process. Driving healthy calcium and phosphate minerals into your enamel, and through a natural process it will bind on and add to the enamel that's there.

4. John Zhu:

   Water is just like wine, the sources and minerals determine the taste, if the water has a lot of calcium, it tastes sweet and chalky. If it's rich in magnesium, it tastes metallic. If it contains sodium, it tastes salty.

5. John Mulchaey:

   This is not just a tiny little bit of calcium, this is a pretty significant detection— I mean, we’re seeing this in data that’s 99 years old.
