Chelation in Metal Intoxiion - PubMed Central (PMC)

2010-6-28 · Chelation therapy is the preferred medical treatment for reducing the toxic effects of metals. Chelating agents are capable of binding to toxic metal ions to form complex structures which are easily excreted from the body removing them from intracellular or extracellular spaces. 2,3-Dimercaprol has long been the mainstay of chelation therapy for lead or arsenic poisoning, however its serious

List of Metals - Science Notes and Projects

Most elements can be considered metals. They are grouped together in the middle to the left-hand side of the periodic table. The metals consist of the alkali metals, alkaline earths, transition metals, lanthanides, and actinides. Properties of Metals. The metals share several common properties, including:

Chelation - Wikipedia

2019-5-4 · Chelation (US: / k iː ˈ l eɪ ʃ ən /, UK: / tʃ ɪ-/) is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central atom. These ligands are called chelants, chelators, chelating agents, or sequestering agents.

alkali metal | Definition, Properties, & Facts

Alkali metal: Alkali metal, any of the six elements of Group 1 (Ia) of the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).

It''s Elemental - The Element Calcium

Metallic calcium was first isolated by Sir Humphry Davy in 1808 through the electrolysis of a mixture of lime (CaO) and mercuric oxide (HgO). Today, metallic calcium is obtained by displacing calcium atoms in lime with atoms of aluminum in hot, low-pressure containers. About 4.2% of the earth''s crust is composed of calcium.

transition metal | Definition, Properties, Elements

2019-4-3 · Transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one. While the term transition has no particular chemical significance, it is a convenient name by which to

What type of metal is calcium

No: Calcium by itself is a metal, but calcium hydroxide is a compound, and compounds are never metals. Note, however, that mixtures of metals, usually called alloys, do exist and are metallic.

Calcium ions | definition of Calcium ions by Medical

calcium channel blocker (calcium channel blocking agent) a drug such as nifedipine, diltiazem, or verapamil that selectively blocks the influx of calcium ions through a calcium channel of cardiac muscle and smooth muscle cells; used in the treatment of Prinzmetal''s angina, chronic stable angina, and cardiac arrhythmias.Calcium channel blocking agents act to control arrhythmias by slowing the
