why is fluorine atom called fluorine?

Because flourine is an element. Not a compound.\n\npeace\nvixklen

The naming of elements precedes the atomic theory of matter, although at the time it was not known which chemicals were elements and which compounds. When it was learned, existing names (e.g., gold, mercury, iron) were kept in most countries, and national differences emerged over the names of elements either for convenience, linguistic niceties, or nationalism. For example, the Germans use "Wasserstoff" for "hydrogen" and "Sauerstoff" for "oxygen," while some romance languages use "natrium" for "sodium" and "kalium" for "potassium," and the French prefer the obsolete but historic term "azote" for "nitrogen."\nThe current system of chemical notation was invented by Berzelius. In this typographical system chemical symbols are not used as mere abbreviations - though each consists of letters of the Latin alphabet - they are symbols intended to be used by peoples of all languages and alphabets. The first of these symbols were intended to be fully universal; since Latin was the common language of science at that time, they were abbreviations based on the Latin names of metals - Fe comes from Ferrum, Ag from Argentum. The symbols were not followed by a period (full stop) as abbreviations were. Later chemical elements were also assigned unique chemical symbols, based on the name of the element, but not necessarily in English. For example, sodium has the chemical symbol 'Na' after the Latin natrium. The same applies to "W" (wolfram) for tungsten, "Hg" (hydrargyrum) for mercury, "K" (kalium) for potassium, and "Sb" (stibium) for antimony.

Ionization energy (1st ionization) increase as you go up and right on the periodic table, so fluorine has the highest.  Similar trends are noted in electronegativity.  Fluorine is the element with the highest electronegativity.\n\nThis trend in electronegativity is seen because going down the group you see the successive atoms have more electron levels which puts the valence electrons farther from the nucleus and easier to remove.  Going to the left on the table you are not adding any more electron levels, but the nuclei are becoming increasingly larger and therefore creating a stronger attraction for the valence electrons.

fluon is a trade name for polytetrafluoroethylene (PTFE) which is also commonly known as teflon.  here is a page with a lot of material properties:\n\nhttp://www.agc.co.jp/english/chemicals/jushi/ptfe/PTFE.htm\nhttp://www.agc.co.jp/english/chemicals/jushi/ptfe/PTFE3.htm\n\ncheers!

Cm (for curium) named for Marie and Pierre Curie\nEs (for einsteinium) named for Albert Einstein\nMd (for mendelevium) named for Dmitri Mendeleev\nLr (for lawrencium) named for Ernest Lawrence\nNo (for nobelium) named for Alfred Nobel\nFe (for fermium) named for Enrico Fermi\nRf (for rutherfordium) named for Lord Rutherford of Nelson\n\noops, u only asked for three :) hope this helps.

Right answer is F) because is given off by alpha (electrons), beta and gamma rays (photons) and breaks molecular bonds.\n\nThat´s it!\n\nGood luck!

Elements with this property are called noble gases or inert gases.\n\nHelium, argon, neon, kyrpton, xenon and radon.

its C2F6,it actually contains two carbon atoms in a molecule and each one of them has three fluorine atoms attached to it,both these carbon atoms are bonded by a covalent bond!!!

CF4 or carbon tetrafluoride has a tetrahedral structure\nthat is the carbon atom at the center of a regular tetrahedron and the F atoms at the corners\nthis is because the carbon atom is sp3 hybridised and has these four sp3 hybridised orbitals bonded with 4 F atoms which orient themselves symmetrically in space so as to balance the forces of repulsion between them and reduce energy thus givin a tetrahedral molecule

Some of the elements were once known by different names than are current, such as Plumbus (Lead), that is why the symbol for ead is Pb.  Also, Sodium used to be known as Natrium, hence Na. etc, etc, etc.

"The transuranium elements are so called because they all lie beyond uranium; that is to say, they are elements with atomic numbers higher than 92 in the periodic table."\nThat's from the web site listed below.\nSo find a periodic chart, and look at all the elements above At. No. 92.

Usually the discoverer names it, but the final decision is up to IUPAC, the International Union of Pure and Applied Chemistry.  The heaviest known elements were discovered during the Cold War, and of course the Americans and Soviets both claimed to have discovered them first and tried to name them after their scientists, so IUPAC stepped in and named the new elements with a numeric code.  That's why those elements have such odd names, like unnilquadium or unnilpentium.  It's just Latin for "element number 104" or "element number 105".  Some periodic tables still use the American names but most use IUPAC's.

The official English name for the element in question is Iron.\n\nThe official symbol for the element is Fe, which comes from the Latin name for iron: "Ferrum."\n\nThe latest international convention of naming iron compounds (using English) is to  call the compound Iron and use Roman numerals to indicate the oxidation state of the iron.  Therefore, FeCl3 is Iron (III) Chloride, while FeS is Iron (II) Sulfide.\n\nOlder methods called Iron (III) compounds "Ferric" and Iron (II) compounds "Ferrous," so that the examples above would be called Ferric Chloride and Ferrous Sulfide.

Atoms form bonds to get to a stable form. All atoms (besides noble gases) want to get a full shell of valence (outside) electrons. To get this full shell, they have to share electrons with others. This is called a covalent bond. \n\nOr, in the case of ionic bonds, a molecule that has extra electrons simply gives electrons to another molecule who wants them. These molecules become positive and negatively charged, and stick together because of magnetic attractions.

Oxidizing agents remove electrons from other atoms to complete a stable outer octet.  Therefore, oxygen and fluorine are oxidzers.  (Hydrogen and lithium, because they can lose electrons more easily than accept them, are reducing agents.)\nSo, of the two oxidizers which is better?  It will be the one that is more electronegative.  Electronegativity increases left to right on a row in the periodic table*.  F is therefore more electronegative than O, so the winner is F.\n'Chemistry is full of exceptions and this rule does not hold for the noble family (VIIIa) because their electron structures are fully satisfied.

Alright, I looked up the history of the spelling of Aluminum.  We Americans don't, in truth, spell it incorrectly.  There are simply two variant spellings.  See below:\n\n"Etymology/nomenclature history\nThe earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from his journal Philosophical Transactions: "Had I been so fortunate as..to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium." [11]\n\nBy 1812, Davy had settled on aluminum, which, as other sources note, matches its Latin root. He wrote in the journal Chemical Philosophy: "As yet Aluminum has not been obtained in a perfectly free state."[12] But the same year, an anonymous contributor to the Quarterly Review, a British political-literary journal, objected to aluminum and proposed the name aluminium, "for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound." [13]\n\nThe -ium suffix had the advantage of conforming to the precedent set in other newly discovered elements of the period: potassium, sodium, magnesium, calcium, and strontium (all of which Davy had isolated himself). Nevertheless, -um spellings for elements were not unknown at the time, as for example platinum, known to Europeans since the 16th century, molybdenum, discovered in 1778, and tantalum, discovered in 1802.\n\nAmericans adopted -ium for most of the 19th century, with aluminium appearing in Webster's Dictionary of 1828. In 1892, however, Charles Martin Hall used the -um spelling in an advertising handbill for his new electrolytic method of producing the metal, despite his constant use of the -ium spelling in all the patents he filed between 1886 and 1903. Hall's domination of production of the metal ensured that the spelling aluminum became the standard in North America; the Webster Unabridged Dictionary of 1913, though, continued to use the -ium version.\n\nIn 1926, the American Chemical Society officially decided to use aluminum in its publications; American dictionaries typically label the spelling aluminium as a British variant"
