Who made up the word chemistry?
I don't know who coined the term, but it's a derivative of the word Alchemy. New scientists in the enlightenment era didn't want to be associated with the BS behind Alchemy, so they made a new name. Something like that.

chemical composition of nucleotides.
Carbon rings with the occasional nitrogen interrupt, depending on the nucleotide, and oxygen bonded to some parts of the various rings. There's also hydrogens attached all over the place to the structure. Adenine and Thymine I believe have two rings. Overall, Carbon, Nitrogen, Oxygen, Hydrogen. DNA adds phosphate and deoxyribose sugars to the mix.

a few questions...
1. why are you a chemist?
Because it's got applications in pretty much every field of industry/science.
2. why ARENT you a physicist?
The short answer - too much math. Also I like biology, which chemistry works better with.
3. what is the nest chemical of them all?
The best chemical... that's a really hard one. Nitric acid is pretty nifty. I like it.

Which element in the periodic table has the largest radius for its valence electron shell?
I'm pretty sure it's Francium (excluding the unstable atomic nuclei).
