Is sodium nuturally found as a pure element?

Not only sodium rather all elements of s and p orbitals with 1 or 2 valency do not exist as naturally found pure elements.\n\nThis is because of their very high reactivity with majority of substances present in the atmosphere, sea and earth crust.

Magnesium is an element, so pure magnesium contains only pure magnesium metal.\nSince magnesium is a somewhat reactive element, it is never found in its metallic form, only in salts and oxides.  Those minerals are mined -- if they have a high enough concentration and are easily and economically accessible and capable of processing -- and the magnesium is extracted though chemical and electro-chemical reactions, similar to those used to extract aluminium.  This involves a lot of electricity as the final purification requires electrolyzing.\nMagnesium is the reason why titanium is so expensive, as to refine titanium, you need to use pure magnesium.

Zinc is by far the best element. I also like plutonium.  It's just fun to say. "Plutonium."

First of all, there is no ZnCl, it is ZnCl2, and there is no NaS, it is Na2S.  ZnCl2 + Na2S would produce ZnS, but ZnCl and NaS do not exist.

Well I can not think of one single thing that has anything to do with sodium politically.\n\nBut commercially they make sodium hydroxide from it and also drain uncloggers like Drano.  Yes it is true that most of the NaOH in the world is made by an electrlysis reaction but some is made by just adding sodium to water.\n\nPlus the manufacturing of chemicals for chemical suppliers to schools all around the country.\n\nThe economy certainly benifits from thousands of schools buying the products that sodium has made and also some schools chemistry departments actually buy sodium metal as a demo or just to show what it looks like.\n\nSodium metal was also featured in a recent episode of CSI: Las Vegas as a weapon.  I don't know if that has anything to do with what you need but it would be something neat to throw into your project if you can figure out how to incorporate it. lol\n\nI hope that some of this is helpful and that you can use it.

The MOST recently discovered element was atomic number 118.  It is being temporarily called 'ununoctium'.  As to WHEN it was discovered... that's a little more complicated.\n\nA team of element-makers at Lawrence Berkeley lab claimed to have made it in 1999, but when nobody could reproduce the find with the lab's methods (even the original lab), their finding was discredited.\n\nIn Spring of 2002 (it took four months) the Joint Institude of Nuclear Research in Dubna claimed to have produced an atom of ununoctium.  This was confirmed by Dubna and the Berkeley lab when each of them produced another atom in 2005.\n\nThe average lifespan of these three atoms was just under a thousandth of a second.  So don't expect any accumulation of the stuff!

If by NA u mean nucleic acids & Na, sodium:\nNA consists of both covalent & hydrogen bonds while Na wil have metallic bonds. \n\npls correct me if i'm wrong as far as denoting NA & Na. Thanks

It isn't. the magnesium ion has a radius of 0.85 angstroms while the sodium ion has a radius of 1.16 angstroms.

pure compound is any element that is not made of other elements eg.hydrogen

The kitchen salt has nothing to do with the natural salt.\nOur kitchen salt, mostly sodium chloride, has not many contact points with the element at the original state, in other words what it is necessary to live. \nThrough the industrial process the salt is chemically wiped put and reduced to sodium chlorite; the minerals and the oligo elements are simply considered impurities and as such they get discarded. Sodium chloride, so treated and unnatural, has nothing to do with its nature, with being in its totality or with genuine salt that, on the other hand hols all the natural elements (84 minerals), the same ones that make our body.\n\nThe kitchen salt affects our body\nThe kitchen salt is a poison for the cells. It gets eliminated or made non harmful by our body sacrificing precious resources. \nThe body has an intelligent protection devise which identifies the kitchen salt as an aggressive poison for the cells and detects in itan harmful an unnatural substance which has to be discarded as soon as possible. This is the reason why our excretory organs are constantly over burdened. The body tries to make the excess kitchen salt non harmful isolating it. Sodium chlorite is surrounded by water molecules which neutralise it, ionising it in sodium and chlorine. This means that the body has no choice but to sacrifice the highly structured water of its own cells in order to make sodium chlorite non harmful. The cells, so dehydrated and deprived by its own vital force, die.

sodium metal is supplied by large chemical supply companies.  you can get some from dupont but you have to buy in large quantities:\nhttp://www.dupont.com/sodium/price.html\n\nyou can get it in small quantities from any number of chemistry supply places that are geared for educational use and small laboratories.  like this one:\nhttp://www.wardsci.com/product.asp_Q_pn_E_9502004_A_Sodium\nwhich offers sodium metal in 100g sticks for around $25.\n\nnote that elemental sodium is extremely dangerous - it is explosive when exposed to water, and even the water vapor in the air can cause a dangerous explosion.  it should be stored under oil and only handled by someone who really knows what they're doing.\nif you don't believe me, check out some examples of sodium explosions here:\nhttp://www.theodoregray.com/PeriodicTable/Stories/011.2/

I believe all the naturally occurring elements found on earth can be found on other planets, for example samples from the surface of mars show that it is composed of basalt and granite, these are igneous rocks (come from volcanoes) that are very common on earth. Elements like iron, silicon, carbon, and  hyrogen are found in a variety of forms

only Sodium Chloride is not.\n\nsimple answer:\ncovalent bonds are between non-metals\nionic bonds are between a metal and a non-metal\n\nthis is because of the large difference in electronegativity between metals and non-metals.\n\nonly sodium chloride has a metal.  the rest are all made only of non-metals and thus covalently bonded.

Sea salt comes in fine or larger crystals. In nature it includes not only sodium chloride, but also other vital trace minerals.\ncheck out this article it should help: http://en.wikipedia.org/wiki/Sea_salt\nAlso: http://en.wikipedia.org/wiki/Table_salt

A pure substance has a formula or symbol so we know exactly what atoms are in it in what proportion. \n\nIn a mixture there can be any material in any proportion.\n\nIn a solution, a type of mixture, there is one substance dissolved in another so that they are all mixed and anywhere we take a sample it will be the same.

Depends on what is meant by *purified*.\n\nIn the absence of minerals in the water, it does not conduct electricity properly.\n\nI made a science project where a light bulb was plugged into the MAINS by means of two wires, and one of the wires was split and had a pyrex bowl filled with destilled water placed in between the two leads. The bulb did not light. I started emptying salt into the water and stirred with a wooden spoon. After a short while, and as the solution became more and more uniform, the bulb would slowly light up.

in huge amounts, it can be.  It is fairly heavy in salt, so the sodium can be a problem; however, many people who have a craving for it are in need of extra sodium.
