Europium is element number 63. Videos about all the elements at http://www.periodicvideos.com/
In this video we make europium and dysprosium nitrate salts we'll need in upcoming videos.
Instead of buying the salts directly from our chemical supply companies we decided to make them entirely using chemicals anyone can buy online or make themselves. In this case europium metal and dysprosium metal with nitric acid.
The europium and dysprosium metal were purchased online from: http://elementsales.com/
The nitric acid was produced in our nitric acid video: http://www.youtube.com/watch?v=2yE7v4wkuZU
The procedures for both salts is rather simple.
First, obtain 2.5 grams of europium. Europium comes in mineral oil so it must be washed off with toluene. Then the europium is placed in a beaker where a total of 10 mL of water is added in small portions. This is added before the acid for safety reasons. After all the water is added and the reaction seems to have slowed down 10mL of concentrated 15.6 molar nitric acid is added.
The solution is then heated to ensure complete reaction of all the metal bits.
For dysprosium:
5g of dysprosium can be directly added to a mixture of 20mL of water and 20mL Nitric acid. Once again, heating the solution ensures complete reaction.
Both nitrates are allowed to dry in the desiccator bag we made last week: http://www.youtube.com/watch?v=XJFfS_YbbYI
Afterward, the nitrates are transferred to vials for storage and labeled.
The europium salt produced will be Europium Nitrate pentahydrate
The dysprosium salt produced will be dysprosium nitrate pentahydrate.
We're going to use these nitrates for some cool upcoming videos so please subscribe rate and comment!
Note: before you ask, no they are not good for any pyrotechnic.

"Europium" is a chemical element with symbol "Eu" and atomic number 63. It was discovered in 1901 and is named after the continent of Europe. It is a moderately hard, silvery metal which readily oxidizes in air and water. Being a typical member of the lanthanide series, europium usually assumes the oxidation state +3, but the oxidation state +2 is also common: all europium compounds with oxidation state +2 are slightly reducing. Europium has no significant biological role and is relatively non-toxic compared to other heavy metals. Most applications of europium exploit the phosphorescence of europium compounds. Europium is one of the least abundant elements in the universe, with only about % in the entire universe.
Europium is a ductile metal with a hardness similar to that of lead. It crystallizes in a body-centered cubic lattice. Some properties of europium are strongly influenced by its half-filled electron shell. Europium has the second lowest melting point and the lowest density of all lanthanides.
Europium becomes a superconductor when it is cooled below 1.8 K and compressed to above 80 GPa. This is because europium is divalent in the metallic state, and is converted into the trivalent state by the applied pressure. In the divalent state, the strong local magnetic moment suppresses the superconductivity, which is induced by eliminating this local moment .
Europium is the most reactive rare earth element. It rapidly oxidizes in air, so that bulk oxidation of a centimeter-sized sample occurs within several days. Its reactivity with water is comparable to that of calcium, and the reaction is

Name Origin
From Europe.
"Europium" in different languages.
Sources
It is never found in nature as a free element. There are many minerals that contain europium, the important of these are bastnasite and monazite.
Primary mining locations are the USA, Brazil, India, Sri Lanka, Australia and China. Annual production is around 400 tons.
Abundance
Universe: 0.0005 ppm (by weight)
Sun: 0.0005 ppm (by weight)
Carbonaceous meteorite: 0.006 ppm
Earth's Crust: 2.1 ppm
Seawater:
Atlantic surface: 9 x 10-8 ppm
Atlantic deep: 1.5 x 10-7 ppm
Pacific surface: 1 x 10-7 ppm
Pacific deep: 2.7 x 10-7 ppm
Uses
Europium oxide (Eu2O3) along with yttrium oxide are used to make red phosphors for colour televisions. A salt of Europium is a component of the newer phosphorescent powders and paints, some of which will glow for days after a few minutes of exposure to light.
A salt of Europium is a component of the newer phosphorescent powders and paints, some of which will glow for days after a few minutes of exposure to light. Europium fluorescence is used to interogate biomolecular interactions in drug-discovery screens. It is also used in the anti-counterfeiting phosphors in Euro banknotes.

Europium becomes a superconductor when it is cooled below 1.8 K and compressed to above 80 GPa. This is because europium is divalent in the metallic state, and is converted into the trivalent state by the applied pressure. In the divalent state, the strong local magnetic moment suppresses the superconductivity, which is induced by eliminating this local moment .
Europium is the most reactive rare earth element. It rapidly oxidizes in air, so that bulk oxidation of a centimeter-sized sample occurs within several days. Its reactivity with water is comparable to that of calcium, and the reaction is

Name Origin
From Europe.
"Europium" in different languages.
Sources
It is never found in nature as a free element. There are many minerals that contain europium, the important of these are bastnasite and monazite.
Primary mining locations are the USA, Brazil, India, Sri Lanka, Australia and China. Annual production is around 400 tons.
Abundance
Universe: 0.0005 ppm (by weight)
Sun: 0.0005 ppm (by weight)
Carbonaceous meteorite: 0.006 ppm
Earth's Crust: 2.1 ppm
Seawater:
Atlantic surface: 9 x 10-8 ppm
Atlantic deep: 1.5 x 10-7 ppm
Pacific surface: 1 x 10-7 ppm
Pacific deep: 2.7 x 10-7 ppm
Uses
Europium oxide (Eu2O3) along with yttrium oxide are used to make red phosphors for colour televisions. A salt of Europium is a component of the newer phosphorescent powders and paints, some of which will glow for days after a few minutes of exposure to light.

Arropame
Arropame
Ya no quiero verme así
Cada vez que pienso en ti
Se confundiesen en una mis sentidos
Termina el mundo al caminar
Yo me derrito al verte andar
Quiero compartir contigo este camino
Arrópame con tu corazón
Y cubre mis sueños con tu calor
Dime lo que tengo que hacer
Tengo ganas de querer
Y sentir que sólo somos tú y yo
Arrópame con tu corazón
Tantas cosas por decir
Entre ganas de vivir
Pero sólo tu calor puede salvarme
Y cuando, te sientas sola a dormir
Quiero que quieras más de mí
Aunque puedo, ya no quiero controlarme
Arrópame con tu corazón
Y cubre mis sueños con tu calor
Dime lo que tengo que hacer
Tengo ganas de querer
Y sentir que solo somos tú y yo
Arrópame con tu corazón
Siento ganas de gritar
Tus labios por ya robar
Y darme despido para éstas lágrimas
Tengo ganas de soñar
Y colar la intensidad,
Que siento cuando te acercas y estás conmigo
Arrópame, arrópame
Arrópame con tu corazón
Y cubre mis sueños con tu calor
Dime lo que tengo que hacer
Tengo ganas de querer
Arrópame con tu corazón
Arrópame con tu corazón
Y cubre mis sueños con tu calor
Dime lo que tengo que hacer
Tengo ganas de querer
Y sentir que solo somos tú y yo
Arrópame con tu corazón, arrópame
Arrópame con tu corazón
