Since only certain one-and two-letter combinations exist as element abbreviations,only a fraction of all strings can be written that way. Good luck! The element symbol images are taken from my world-famous Periodic Table Table . Click on any letter to see information about and samples of that element. (Use only the letters a-z and space.)

Well, bang the drum and play the victory bugle. What you did just there is sing a googol. *ding* One with a hundr...
