Can someone recommend me a site where I can find the spectrum of all elements ?

Your nearest rainbow? Just kidding!\nTry this site: http://physics.nist.gov/PhysRefData/Elements/legend.html

No. Look at the periodic chart, also called the table of elements. Its even in the dictionary. So is alkaline. Finding that would have been easier than going to Yahoo answers, had you tried.

um i don't know if this site has it, but you might want to try chemguide.co.uk :) it's a pretty good site.

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

Take radium and subtract two from its atomic number. Then find the element with that result as its atomic number. I'm too lazy to see what that is right now.

um...right...please retype the question. if you want to know more about the branches (inorganic, organic, physical etc) try www.chemistry.org

Try Chemistry.com.  It may not directly help you with 'chemistry', but the site is supposed to be geared toward helping you find 'the one' with advanced techniques based on the things that users would define as 'chemistry'.\n\n(Sorry for all the quotes.)

By using spectra. Each element has characteristic frequencies of light that it emits or absorbs. If light from the star is spread out into a spectrum (like a rainbow), there will be dark lines for absorbtion and bright lines for emission. By identifying the chemicals that correspond to those lines, we deduce the composition of the star.

www.alloy.com ....... yeah

you need a periodic table... just look for the symbol NA... and the atomic number 15, also look for it on the table.. it shud be under the 2-3 letter symbol of the element.

STN, owned by Chemical Abstracts Society, has dozens of databases for this purpose.\nhttp://www.cas.org/stn.html\nAlso, look at the Diaglog service, by Questel.Orbit.
