I am periodically the number 79. Long ago some attempted to make me from 29, but learned it couldn't be done. If you add me to 80 I appear to be 47 temporarily.
What am I?

accordionman Jun 24, 2004	This is the first chemical question I can answer on this site. This was an awesome teaser!
doggyxp Jun 24, 2004	This teaser, although it was easy, was fun and enjoyable. Great job!
crystalstar Jun 24, 2004	This was hard for me! Well I thought it was incredible and I added it to my faves!
shelleyz Jun 25, 2004	this teaser was so easy
Varthen Jul 01, 2004	Isnt this supposed to be in the science category?
vbfreak55 Jul 26, 2004	i don't like science and the table of elements. too hard for me. i also thought it should be under the science catagory, although that might give it away.
username Aug 18, 2004	easy, easy, easy!
nunya Jan 08, 2005	clever!
southernbby4 Jan 15, 2005	this was totally hard but when igot the answer i thought DUH
whoelsebutme09 Feb 17, 2005	that was pretty easy even 4 me!
MULA Mar 04, 2005	THATS A GOOD ONE
kcelf27 Apr 25, 2005	Well my brain must be made of some sort of mushy element because I had no clue at all. You guys must all be science buffs!
smarty_blondy Oct 01, 2005	Very clever, i had no idea it was elements you wrote about. Awesome job on this one!
lukeschett Mar 26, 2007	I thought that people wanted to make lead into gold.
mumbojumbo1234 Aug 13, 2008	It's funny... I didn't know the numbers for sure, but this is just one of those rated-harder puzzles that took no effort on my part. Just the wording alone gave it away, I suppose, even without the periodic, though once I thought about it that was a dead giveaway.
J-Mac Aug 13, 2008	Very good! I liked this one. When I saw 29 I was thinking it should be 82 - I had Lead on my mind. Thanks! Jim
craniac Aug 13, 2008	It was easy. Just pull up a periodic chart and look.
zxyggrhyn Aug 13, 2008	My Idea: Something '79' related to time. I was misled by the word 'periodically'! Good Job!
bradon182001 Aug 13, 2008	Nice one. Thanks for posting.
emu77alu02 Aug 13, 2008	I knew that it had to do with the table of elements, but I wasn't about to go hunt down my high-school chemistry books and charts to figure out which elements they were. This was pretty good and informative!
doehead Aug 13, 2008	Good Quiz. My Chemical background made it easy for me.
Ysemay Aug 13, 2008	I really liked this one.
phyllisa Aug 13, 2008	GREAT teaser - I had to look up Hg, but got the rest!!!! Got my brain working!!!!
kwelchans Aug 13, 2008	I knew it had to do with elements, but I had to pull up a periodic table to find out WHICH element.
jennsingergirl Aug 13, 2008	Clever!! Good job!! =)
auntiesis Aug 13, 2008	I don't know the numbers , but the wording gave it away. Very good teaser even for this dummy.

brainyboy615 Aug 13, 2008	Awesome! Great Teaser!!!
Jazzy_Sammy_13 Aug 13, 2008	Koolio
kauphi1976 Aug 13, 2008	golden ! i actually got it looking at it ! and i thought i hated chemistry !
monkey289 Aug 13, 2008	Very easy and fun!
FatHead Aug 16, 2008	I had to figure it out, but I succeeded! (But I thought alchemists tried to make gold out of lead?)
Mandy7 Aug 13, 2011	i no this is off topic, but i lik gems n gold n stuff lik that cuz itz pretty n shiny and they cost a lot but i lik 2 pretend that i hav such jewels cuz mah sister likz 2 play games lik that
Mandy7 Aug 13, 2011	haha thatz... odd, i guess but good point, fathead (dont mean 2 be rude, but that IS ur username, right?) srry bout that
gaylewolf Aug 13, 2011	This isn't my favorite type of teaser but the majority of folks did like it! As for me, once again, the comments provided an ELEMENT of surprise and a good laugh! Come on Doehead - don't let me down - let's hear your comment on this one!
doehead Aug 13, 2011	My response to gayle. My chemistry studies in college made this one worth about $1740 an ounce. I'll take about 2 tons if your giving it away.
wordmama Aug 13, 2011	Didn't need the periodic table; the line 'long ago some attempted to make me from....' gave it to me. Didn't matter from which element; the "me" was gold!
Mandy7 Aug 13, 2011	ok............ thats..... odd i guess? wat wuz that all bout???????
rockstar1009 Aug 15, 2011	This one was fun . . . possibly my favourite yet. I knew the answer was gold, but the copper clue threw me off (I too was thinking lead, but I know copper is 29). I didn't know Hg was 80, but I did know Au was mixed with Hg during gilding processes & while I didn't know the alloy would look like Ag, I assumed it must based on the clues. Great, fun teaser!
