any one know what does K,L,M,N....shells mean in chemistry....what does these letters stand for?
493740
no they r not named...k,l,m,n are shellls...k is nearest to the nucleus....k can support 2 electrons, l can support 8,m can do 18 but in some cases it is 8 and n can support 32.

Molarity (moles/liter) is abbreviated M, not to be confused with molality (moles of solute/kg of solvent), which is abbreviated m. Math problems involving moles/molarity aren't too bad at all... all you do is plug in numbers and solve.

Here is the answer.. Just remember periodi table...\nElements on left most side are electro positive and elements on right most are electro negative. (The last row is nobel gases..so leave it)\nNow Cl- belongs to right most side... its more electro-ve\nRb, Ca are on left side.... they are electro positive(They will give  electron with out much force)\nSi, S are in middle-- their properties are in between...\n\nThats it!

Subscript refers to the position and size of a text.  As in H2O, the 2 shouldn't be this big.  It should be smaller and at the bottom of the H.  In chemistry, an subscript gives information as to the number of atoms of that kind there are in one molecule.  So in that example, there are 2 hydrogen atoms and one oxygen atom to form one water molecule.\n\nSuperscript is a smaller texte at the top.  Like in O-2, the -2 should be superscript.  In chemistry, it give information to the number of oxydation.  In that example, it would mean that the oxygen ion as two extra electrons and is willing to bond to a positive ion.

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.

Generally it doesn't stand for anything. It's just that. "Okay."\n\n'kk' is just Net Speak. Half the time it doesn't mean anything. Just like saying "WOMG!" the 'W' doesn't stand for anything. It just makes saying 'OMG' more funny, especially if you are picking on internet newbies.

it is very simple, the shells, subshells actually represent energy levels in the atoms. it is just like big building having different storeys and them again the rooms. You can compare storeys as shells, and individual apartments as subshells and the rooms in each apartment as orbitals where we the electrons are revolving

s,p,d,f are the names of different kinds of electron orbitals.  they correspond to different values for the angular momentum quantum number "l".  \n\ngoing from s -> p -> d -> f and so on means an increase in the electron's angular momentum about the nucleus.  s means the l quantum number is 0; p means l = 1, d means l=2, f means l=3.  \n\nrereading the question, maybe you mean what do the letters stand for?  it has to do with the way electron orbitals are studied, which is via emission spectroscopy.  the names were originally given to describe different kinds of spectral lines and they stand for:  sharp, principal, diffuse, and fundamental.

Tungsten, or in German, Wolfram. This is why the symbol is W.

By "shells," do you mean the energy levels of the electron orbitals?  If that's what you mean, all you do is look on the period table and count how many rows from the top the element is.  So H and He each have one electron shell, C, N, O, F, etc. all have two, Si, B, Na, Cl, etc. all have three, and so on.  Sorry about the scattered examples (I was listing them by memory), but hopefully you get the idea.

a.  Expanded shell/with 6 pairs of electrons around the central molecule.\n\nb.  Expanded octet with four shared pairs and one unshared pair.\n\nc.  Not sure but free radical with one double bond between an oxygen and and Cl.

Which science? In Chemistry, Na is the symbol of Sodium (Natrium, in latin). But Na03 makes no sense, there's no such isotope.\n\nEDIT: People, he didn't type an "O" from oxygen but a zero. Try copying it to your notepad and you'll see the difference.

K stands for Kilo, the European metric equivalent of 1000. The metric system has grams, and kilo grams (thousands of grams). Americans have used it for quite a while in anticipation of conversion the the metric system.
