Assignment One                    Due 9/14/00

Learn the names and symbols for the first 30 elements (hydrogen through zinc) listed in order of atomic number plus Ag, Au, Pb, Sn, Hg, Br, I and Rb. (Check the original assignment for the correct and entire list). You need not learn the atomic number, but you must be able to go from the name to the symbol as well as from the symbol to the correctly spelled name.  

Remember that the first letter of an atomic symbol is ALWAYS a capital and the second letter is ALWAYS lower case.  Therefore, NA is incorrect and Na is correct, etc.
