Europium - the 63rd element on the Periodic Table

Name: europium
Symbol: Eu
Atomic number: 63
Atomic weight: 151.964 (1) g
CAS Registry ID: 7440-53-1
Group number:
Group name: Lanthanoid
Period number: 6 (lanthanoid)
Block: f-block
Melting Point: 822 튏
Boiling Point: 1529 튏
Electron Configuration: [Xe]6s24f7 Oxidation States: 3, 2


History
(Europe) In 1890 Boisbaudran obtained basic fractions from samarium-gadolinium concentrates which had spark spectral lines not accounted for by samarium or gadolinium. These lines subsequently have been shown to belong to europium. The discovery of europium is generally credited to Demarcay, who separated the rare earth in reasonably pure form in 1901. The pure metal was not isolated until recent years.


Production
Europium is now prepared by mixing Eu2O3 with a 10%-excess of lanthanum metal and heating the mixture in a tantalum crucible under high vacuum. The element is collected as a silvery-white metallic deposit on the walls of the crucible.


Properties
As with other rare-earth metals, except for lanthanum, europium ignites in air at about 150 to 180oC. Europium is about as hard as lead and is quite ductile. It is the most reactive of the rare-earth metals, quickly oxidizing in air. It resembles calcium in its reaction with water. Bastnasite and monazite are the principal ores containing europium.


Sources
Europium has been identified spectroscopically in the sun and certain stars. Seventeen isotopes are now recognized. Europium isotopes are good neutron absorbers and are being studied for use in nuclear control applications.


Uses
Europium oxide is now widely used as a phospor activator and europium-activated yttrium vanadate is in commercial use as the red phosphor in color TV tubes. Europium-doped plastic has been used as a laser material. With the development of ion-exchange techniques and special processes, the cost of the metal has been greatly reduced in recent years.


Cost
Europium is one of the rarest and most costly of the rare-earth metals. It is priced about about $7500/kg.

When I get older losing my hair,
Many years from now.
Will you still be sending me a valentine
Birthday greetings bottle of wine.

If I'd been out till quarter to three
Would you lock the door,
Will you still need me, will you still feed me,
When I'm sixty-four.

You'll be older too,
And if you say the word,
I could stay with you.

I could be handy, mending a fuse
When your lights have gone.
You can knit a sweater by the fireside
Sunday mornings go for a ride,

Doing the garden, digging the weeds,
Who could ask for more.
Will you still need me, will you still feed me,
When I'm sixty-four.

Every summer we can rent a cottage,
In the Isle of Wight, if it's not too dear
We shall scrimp and save
Grandchildren on your knee
Vera ,Chuck & Dave

Send me a postcard, drop me a line,
Stating point of view
Indicate precisely what you mean to say
Yours sincerely, wasting away

Give me your answer, fill in a form
Mine for evermore
Will you still need me, will you still feed me,
When I'm sixty-four.

Hopefully I'll be able to collect my pension cheque (if there is anything left in the pot in Canada) when I turn 65.

I'll represent the 19th prime number: 67

[Atlas]

68 and....

[Atlas]

69 Baby, yeah!

[nicdoering]

Ohhhh... I've been waiting for 69 and Atlas beat me to it. It was my house number when I used to live with my parents - you can imagine the teasing I got at school for that...

So I'll do SEVENTY instead.

[once again]

SEVENTY ONE is my IQ on a good day

I was concepted in 1974, my guess is sometime in the summer.

Hence, 74 is a special number for me.
