2010-5-12 · The elements can be classified as metals, nonmetals, or metalloids.Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire).Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid).
Fluorine''s special status also stems from the ''fluorine factor'', the ability of this little atom to fine-tune the chemical properties of an entire molecule. For example, replacing hydrogen with fluorine can protect drugs from degradation by metabolic enzymes, extending their active lifetimes inside the body.
2019-4-18 · Fluorine is a chemical element with syol F and atomic nuer 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon. Among the elements, fluorine ranks
2019-4-16 · Fluoride (/ˈflʊəraɪd, ˈflɔːr-/) is an inorganic, monatomic anion with the chemical formula F− (also written [F]− ), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used
Calcium is a silvery white metal. The surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium
Neither one. . Sodium hydroxide, or NaOH, is neither a metal or a non-metal. It is an ionic compound. It is composed of sodium, which is a metal, and oxygen and hydrogen which are non-metals.
Fluorite, a mineral of calcium, is a compound of the metal with fluorine. Analysis shows that a 18.66 g sample of fuorite contains 9.590 g of calcium. How do you calculate the mass of fluorine in the sample?
2019-3-20 · I keep hearing from several websites and videos that Fluorine seems to like bonding to Calcium specifically; can someone please tell me why? I can''t seem to find a clear response on the internet. Fluorine has a high affinity to Calcium, more than other elements. Why is that?
The metal calcium is an Alkaline Earth element, which is found in Group 2 of the periodic table. All the Group 2 elements have two valence electrons, and these elements want to loan them both out.
Calcium is a Group 2 metal. Fluorine is a Group 17 gas. Towards the right of the Periodic table, ELEMENTS tend to get smaller as the increased nuclear charge exerts a greater attractive force on the valence electrons.The small fluorine atom tends to attract electrons, and is energetically most stable when it forms the #F^-# ion.. On the other hand, calcium is a large Group 2 metal.
