Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. Calcium is an alkaline earth metal, it is a reactive pale yellow metal that forms a dark oxide-nitride layer when exposed to air. But, before finding, let's learn the basic concepts behind atomic number… Atoms are made of three different kinds of subatomic particles: neutrons, protons and electrons. Calcium is a chemical element with symbol Ca and atomic number 20. The number of electrons in each of Calcium's shells is [2, 8, 8, 2] and its electron configuration is [Ar] 4s 2. Connected lines with dots. Calcium is a chemical element with symbol Ca and atomic number 20. Now, in order for an atom to be an atom of calcium, it … If Z, the atomic number = 20, there MUST be 20 nuclear protons, and the element MUST be calcium, with 20 electrons associated with it. 1 answer. Can you explain this answer? SC85-1 (11.87172 eV) Ref. An alkaline earth metal, calcium is a reactive silvery metal that forms a dark oxide-nitride layer when exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium. Number of Protons = atomic number = 20. Unlike most transition metals, calcium and its compounds exhibit a low toxicity. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. A man weighing 70 kg. The atomic number of calcium-42 is 20. , s. Log in for more information. It is one of four stable isotopes of calcium. Calcium lose 2 electron when forming an ionic bond with another ion. A basic element found in nearly all tissues. Calcium (Ca). About 99 per cent of the quantity in the body is used for building strong bones and teeth and the remaining one per cent is used by the blood, muscles and nerves. 20 electrons (white) occupy available electron shells (rings). The atomic number of calcium and argon are 20 and 18 respectively, but the mass number of both these elements is 40. asked Feb 5, 2018 in Class IX Science by saurav24 Expert ( … Calcium (C a) has atomic number 2 0 and mass number 4 0.
