Sodium /ˈsoʊdiəm/ is a chemical element with symbol Na (from Ancient Greek Νάτριο) and atomic number 11. It is a soft, silver-white, highly reactive metal. In the Periodic table it is in column 1 (alkali metals), and shares with the other six elements in that column that it has a single electron in its outer shell, which it readily donates, creating a positively charged atom - a cation. Its only stable isotope is 23Na. The free metal does not occur in nature, but instead must be prepared from its compounds. Sodium is the sixth most abundant element in the Earth's crust, and exists in numerous minerals such as feldspars, sodalite and rock salt (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the earth's minerals over eons, so that sodium (and chlorine) are the most common dissolved elements by weight in the oceans.
Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Many sodium compounds are useful, such as sodium hydroxide (lye) for soap-making and sodium chloride for use as a de-icing agent and a nutrient (edible salt).

This is one way sodium metal can be isolated using NaOH and Mg. Mg has a strong enough desire for oxygen to tear it from the NaOH, leaving ingots of elemental sodium behind. 2Mg + 2NaOH = 2MgO + 2Na + H2 Thanks to NurdRage for the equation. http://www.youtube.com/NurdRage #NightHawkInLight
Here I do the ever-popular sodium in water demo, but before that I talk a little bit about the element and show a few of its properties. Stick around until the end and you'll get to see my first on-screen appearance in one of my videos! Trivia: There was actually one other video where you got a short glimpse of me, which one was it?

Honestly this dude is awesome, ever time I go over there the lawn just gets destroyed, things catch fire that aren't supposed to, and hes just a generally cool guy, thanks Travis! This is part 2 from my liquid metal bullets experiment! Last week we tested how these bullets preform by shooting them into a tank of water, this week we got to have some fun! We shot watermelons, cinderblocks, starting fluid, and a bunch more. Its a long video, but totally worth staying till the end because you get to see me choke on a bug haha. The first ...

Sodium and Your Body - Nutrition Tips - as part of the expert series by GeoBeats. Sodium is one of those things that people have a lot of questions about, particularly my cardiovascular patients. Interesting thing about sodium is not everybody is as sensitive as we have kind of been led to believe. So we will start there is that some people may have a sensitivity to sodium with regards to high blood pressure, not everybody. S, that said, how much should you have in a day? No more than a tea spoon. That is the general recommendation for adults in the western world. It is no more than a tea spoon and that is extra salt. That is the extra salt you find in processed foods. That is the salt you put on at the dinner table. That is the salt you cook with. It is not naturally occurring sal...
So today we will find out what happens when you combine two active alkali metals - sodium and potassium. For this, I took a piece of sodium and potassium, and began to rub them against each other within the evaporating dish. To prevent the alloy from oxidation by being exposed to air, I’ve decided to conduct the melting of sodium and potassium under a layer of kerosene. Since potassium is a very soft metal, it immediately deforms and wrinkles. Over time, a liquid alloy of sodium and potassium is formed at the point of contact of the two metals, which is instantly being covered by a gray oxide film. This alloy remains in liquid state from minus 12 to plus 785 degrees Celsius. It is a very dangerous alloy because it is more active than sodium or potassium on their own. I’m filling the syring...

[Lyrics The The - Sodium Light Baby] As I sat in the back of that old taxi cab. Waitin' for the evening to come. On every street of this city I heard you call my name. You're the strangest feeling I ever had. The strangest feeling. You're the strangest feeling I ever had. The strangest feeling. From the day that we are born Until the day we die We are hostage to our hearts' desire. And though I ride this city I can't escape from you. And when I look up to the stars I wonder Can the world really be so cruel? You're the strangest feeling I ever had. The strangest feeling. You're the strangest feeling I ever had. The strangest feeling. Tonight the wolves are howling I can't escape from you. A yearning past denying I will surrender to. You're the strangest feeling I ever had. The strange...

The local council is currently replacing the old sodium arc streetlights in our area with new fancy LED ones. I was able to compare the two types of light side by side while taking Mr Bones (the dog) for a walk.

Thirst and appetite has generated much study and research about the physiological, endocrinological, and pharmacological mechanisms that influence water intake. However, in this book, other concerns have been emphasized, such as the significance of brain mechanisms in the subject matter. This book, consisting of 11 chapters, starts with a basic description of thirst then to an analysis of basic physiological mechanisms that determine water intake. Another topic also discussed in this book is various experimental paradigms that resulted to the dual-depletion theory of thirst. The n...

Don't call, don't write, don't speak my name
Though we've tried this twice
I'm just another face
Even when you're running out of luck
You think we'll get it right this time
Get it right, all right, all right, all right
Run, in another five months you'll be alone
And you'll drive around this empty town
To the places, to the places we used to go
You gotta get used to going out
And you'll drive around this empty town
To the places, to the places we used to go
By now, by now, I'm sure you've heard
So you called me yesterday
But I had nothin' to say
Message said I'm running out of time
So, so much for the honesty
Because after all, you know you've won
Run, in another five months you'll be alone
And you'll drive around this empty town
To the places, to the places we used to go
You gotta get used to going out
And you'll drive around this empty town
To the places, to the places we used to go
I'll write you one more song
Spell it out for you to leave you
Where you're standing now
You're running out of lies
So, so much for the honesty
Because after all, you know you've won
Run, in another five months you'll be alone
And you'll drive around this empty town
To the places, to the places we used to go
You gotta get used to going out
And you'll drive around this empty town
To the places, to the places we used to go
To the places, to the places we used to go
