Where can thallium be found? Is that chemical used in hospitals?

Thallium is deadly here is a link\n\nThe Soviets use it to poison people\n\nhttp://en.wikipedia.org/wiki/Thallium

1. M1X1 (no subscripts), because alkali metals are +1 and halogens -1.\n2. M2X1 (subscript 2 for the metal), because group 6a elements are -2 in binary compounds\n3. MX2, because alkaline earths are +2.\n4. MX (subscripts each 1) because alkaline earths are +2 and group 6a elements -2.\n5. MX3, because group 3a metals are mostly +3. An important exception is thallium, which is either +3 or +1. So thallium chloride could be TlCl or TlCl3.

Nothing. You are either thinking of a heavy metal like lead that could interfere or you have an irrational fear that fluoride in your mouth is deadly.  When the x-ray is processed with tap water for its rinsing and gets chloride (a different halide) on it that would be an example to show why this is not a problem.

Look at the big cardiac hospitals, depending on location.  I'm in Tennessee, good places would be Vanderbilt University Hospital in Nashville or University of Alabama at Birmingham (UAB).  Most large cities are a good source...New York, Chicago, L.A., Dallas just to name a few.  Sorry I can't be more help, giving you what I know.

Thallium doesn't have any fissile isotopes so it'd be useless as a form of energy.  If it is Thorium that you were refering to (as santosh_k suggested, pity most of the rest of his answer is nonsense) then a Thorium Breeder is actually a nuclear reactor so the question to ask would be why we use Uranium instead of Thorium as the fuel for our nuclear reactors.\n\nThe first reason is that Uranium from the ground is useful after some processing while with Thorium we have to run it through a reactor to breed Uranium 233 (which you won't find much of in the ground but is quite good at running a reactor).  If you can get more Thorium 232 to convert to Uranium 233 then you can create more fuel than you consume which is what a Thorium reactor does (at first you'd use Uranium 235 from the ground as the fuel).  The Canadian reactor design is well suited to use as a Thorium breeder and the Indians are looking very closely at the technology because they have little Uranium but a lot of Thorium, the US also operate a Light Water Thorium breeder.\n\nMost Breeder research has been in Liquid Metal cooled fast breeders which produce Plutonium 239 from Uranium 238 (while the Thorium breeders produce Uranium 233 from Thorium 232).

Los Alamos national lab has a good periodic table/ elemental factoids.\n\nLanthanum is La.  It is the beginning of the "Lanthanides".

It depends on if you are looking at large quanities or just any ammount goes. It also depends on if you are looking at elements that are only found in compounds or not. Oxygen, hydrogen, argon, carbon, nitrogen, alluminium, silicon, iron, tugstan, lithium, potassum, titanium to name a few. almost all of the elements can be found near the earth's surface except those that are man made, usually the extremly heavy ones like plutonium.

In a doctor's office, or in a hospital. \n\nBest of luck in your search!

It is not a combination of iron and tin, or anything else besides protons, electrons, and neutrons.\n\nThere's a naturally occurring ore called bauxite, which was discovered near Les Baux in the south of France, which is refined to produce aluminum.\n\nAt this link   \n\nhttp://volcano.und.edu/vwdocs/minerals/bauxite.html\n\nthere's a pie chart showing where it is mined today.  A lot of it comes from Australia, but that's not the only source.

Element 118 may have been found about two weeks ago:\n\nhttp://www.fogcityjournal.com/news_in_brief/bcn_livermore_labs_element_118_061016.shtml

because not all of it has turned into lead yet. a half life extends forever. the part that has not decayed is still uranium.

Most psychiatric hospitals have drug/alcohol units. Some regular hospitals do...I would check their first. If you lived in AR I could tell you some places.

Do you mean Aultman Hospital?  If so it's at http://www.aultman.com/

Tungsten mostly, but there are other metals used. There are also gasses that glow too in bulbs that have no filiment wire.

It was discovered in 1817.  It was found associated with Tellurium.  During this time it was found in minerals such as crooksite and clausthalite.

Good question.  Don't believe anything they tell you in the health store.  I worked in a steel foundry and shovelled a lot of that stuff in the furnace and the warning on those elements were pages and pages.  So, why do they sell it in a heath store?\n\nTake the example of chromium.  The stuff is toxic and causes cancer.  Yet, you go into a health food store and they will tell you its great for diabetes and weight loss.  They should be arrested.  Chromium is used to for stainless steel.  \n\nAnother example is manganese.  The stuff causes parkinsons, but they sell it in stores.  They also sell Silicia, which causes autoimmune diseases like lupus.  \n\nThere are some elements you do need like iron.  I was low in iron myself and had to take it.  (iron is toxic to children)  \n\nSome people have Wilsons disease which is too much copper.  \n\nBut, most of these can be measured by a doctor.  I would never take anything other than a multivitamin.  The rest of the stuff at the health food store is very risky to your health.
