Francium + Water = Best party favor ever
Francium is extremely rare, but that would be awesome.

Francium is extremely rare, but that would be awesome.
In fact, there is only 20g of francium on earth at any given time. It's mostly created as a by-product of spontaneous nuclear fission in the earth's crust, and then it goes over spontaneous fission not too long after birth. This means It's also fairly radioactive.

Giant radioactive explosions anyone?


Bismuth, the incredible crystallizing metal!

Pretty crystals:

Anyone want to try and figure out how to home-grow bismuth crystals?

On a side note, the "Periodic Table of Videos" is a pretty awesome arrangement of vids on youtube that talks about all of the elements, like Uranium:

Francium's the rarest element after Astatine, both are radioactive, surprisingly. Astatine having only a bunch of natural atoms actually existing at any one time.

I was thinking about how much of an exact science chemistry is. There isn't much room for theoretical crap(until you get high up in the table when everything is theoretical). Every elements always has the same properties and behavior so you can always tell how elements will react with each other. It's amazing how all the known elements can be arranged in such a simple to understand method. How they perfectly line up in order of similar properties and increasing reactivity.

Memorizing general chemistry stuff for my first quiz in an hour. You know, common polyatomic ions, naming molecules; polyatomic ions; and acids, greek prefixes, SI units.

Yeah once you have the basics down, you pretty much understand the whole of chemistry. Don't be fooled though, elements react a tad differently once you go down the groups. They start ignoring that whole Octet rule stuff, since they get 5 extra orbitals (d orbitals) from the 3rd period down, and then 7 more extra orbitals (f orbitals) from the 4th period down. I've seen compounds whit specific metals where the metals would have 5 covalent bonds all on some other metal, while having like 3 other covalent bonds going out towards stabilizing groups to keep the molecule from exploding.

But these exceptions make allot of sense when you have the basics down too, so it's really down to what you learn in high school and 1st year college really.

Lots of chemistry
Oh noes! the expreiment turned cookie monster brown!

ahh chem. so fun, i like messing with cornstarch and vibrations

Do you like it because the teacher is a hot female? :D



I get biology
Have fun memorizing a bunch of names you'll forget in about a year.

If only biology was solely concentrated on FUNCTION of organic parts, then it could be fun like mechanics class except the machine is you. Learning how something works is allot more interresting then learning what the Greeks named it. Although it's true that a part of biology focusses on function, but it's undermined by the fact that you need to memorize the name foremost.

On to Bismuth, do you guys want to try and find some info on how they grow this stuff? I could probably obtain some bismuth and then make crystals, but I dunno how. Although, I could always exploit the electronic archives back at the library...

As far as I know, I only have to take basic chemistry (CHY 121) for my computer engineering degree.  I know I have physics for engineers next semester.  So far, this chemistry class has been a review of AP, which I took junior year.
