everyone knows that H2O is water, but what substance has the longest chemical symbol? or, what substance do you know whith a rather long chemical symbol.
Try the chemical formula for DNA.
Quote from: another_someone on 17/05/2007 16:12:30Try the chemical formula for DNA.Yes, but a diamond's formula is longer (it's a polimer, the molecule is as long as the entire crystal. Of course I choose the simpler it came to mind).
P.S., there is a shortcut for DNA/RNA. Each monomer (repeating unit) is only different in the identity of the base that is present. There are only 4-5 different bases that are found in DNA/RNA - each is represented by a letter (e.g., G for the guanine base). The strand of DNA is then represented by which base is present in each repeating unit, such as GTCGAGCACGCT.
Strictly speaking the elemnts have symbols and compounds have formulae. Up until recently the chemical symbols were 1 ro 2 letters long. IUPAC decided to do away with the arguments over the names of newly created heavy elements by naming them after the (greek prefixes of) the atomic number so, for example element number 121 in the periodic table would be called unbinubium (I think) and have the symbol Ubu which strikes me as even more silly than having an argument over the name.Heres some explanation.http://www.chem.qmul.ac.uk/iupac/AtWt/element.html
