Rubidium

[Racoon]

an Alkali metal, and metallic element number 37, Rb,

what makes this so highly reactive? :(

 

Where is this mineral found? and is there any significance to it?

 

Some basic chemistry, yes, but curious nonetheless

I can say why it is so reactive.

It is because it has only one valence electron present at a great distance from the attractive nucleus. So you can imagine that the protons cannot 'hold' it well with their positive charge. -A very low class, but effective and valid explaining method.

 

So Rubidium loses that outermost electron very easily. This electron makes it do all its reactions.

And if you need some other good info on it, check this site out.

an extract from there (If you're in a bit of a hurry)

 

The element is much more abundant than was thought several years ago. It is now considered to be the 16th most abundant element in the earth's crust. Rubidium occurs in pollucite, leucite, and zinnwaldite, which contains traces up to 1%, in the form of the oxide. It is found in lepidolite to the extent of about 1.5%, and is recovered commercially from this source. Potassium minerals, such as those found at Searles Lake, California, and potassium chloride recovered from the brines in Michigan also contain the element and are commercial sources. It is also found along with cesium in the extensive deposits of pollucite at Bernic Lake, Manitoba.

May I know the context of the curiosity?:(

[YYYY]

Rb is found in Sea Water and in Land based salts

Probably watching that brainiac show where they blow up a bath tub with it and water :( dangerous stuff!

Hahhaha. You're going to have a hard time finding rubidium in its pure form. I'm pretty sure that it will react with moisture in the air. :hyper:

what I interest in is the relationship between the "Rubidium"and the "BEC":shrug:

You'd better post about it soon then.

Maybe I'm not quite with it! :doh:

 

What is "BEC"????? :)

Bose-Einstein condensate

 

For me ,BEC is a very foundmental to my original idea:Angel:

Thanks rn86

 

Fascinating things they can do with lasers and magnetic fields :confused:

 

Wonder if a black hole possesses similar characteristics -

 

A massive explosion creates an area at the origin of the explosion devoid of all matter forming a cold spot ...... maybe close to or at absolute zero, and an even greater vacuum than the rest of the space surrounding the explosion site.

 

'X' amount of debris from the explosion passes a critical point where the debris escapes into space. 'y' amount of debris which has not reached the critical point is sucked back to the center of the origin of the explosion.

 

Since the explosion site is so cold the material sucked back is brought to its lowest energy level close to or at absolute zero and the dense mater of the black hole is formed.

 

Since all matter is polerised - perhaps the way in which the atoms in the black hole at their lowest state do not randomly stick together but rather align polarly creating a mono pole at the center and concentric layers of positive and negative atoms of BEC!

 

The atoms forming the initial sphere still possess week forces of attraction but not great enough to flip away - bit like holding two like poles of bar magnets together, they wish to separate but the force of you holding them together overcomes their repulsion.

 

Hey maybe that is why their is no known area in space at absolute zero; even in a black hole the atoms at the center still possess week forces of attraction and repulsion, if remember right approximately 3 degrees Kelvin is the lowest temperature.

 

Look forward to your thoughts :xx:

:hihi: Jay! You probably interpreted that correct!:) Yeah I saw that when they blew up the bath tub...pretty amazing....what sort of explosion can you get by mixing it with acid? Also, how does it burn? Quite fiercly I expect...Has anyone ever tried Francium? It's most stable isotope is stable for 20 mins, so it should be possible to test it...How would that sort of explosion compare to othe explosives?

Doesn't that sort of answer your question? :(

Francium is extremely rare, in fact it hasn't been photographed in any considerable amount. I think the largest sample was on the order of a few thousand atoms.

Good luck trying to find some to blow up a bathtub.

here's that rubidium and cesium video

 

Alkali Metals Video :(

here's that rubidium and cesium video

 

Very very very nice. I wish to purchase some cesium soon. :cup:

 

By the way, does anyone know how they made/bought "dissolving vials"?:cup:

[Jay-qu]

Good question, Ill look into it! That would be a very handy thing to have :)
