## Comments

i disagree with the title

Whoah... Confuuuuusiiiiinnnnng.... So many numbers...

very very original I love it!

boring

Creative trick but not really a series in a math sense in my opinion... also, your numbers don't seem right for this .. why isn't

Actinium (Ac) and Silver (Ag) at beginning of series? You seem to start with Rutherfordium (Rf) which is 104.. so, how do you get to Dysprosium (Dy) andd 66 at the end... what am I not understanding?

Sorry, I'm in the same boat as the comment above. I think what you've got is the order of elements you've put together to make the really strong drugs you must have been smoking when you came up with that one

sorry, the table i looked at said that 104 was element 104 (unkown), yup, it was out of date, sry ppls

That may not be impossible but it is definitely the nastiest teaser I have seen on here yet!

whyy........

There are elements of genius here -- but a little sloppy -- Like Einstein! -- google "periodic table" to find a really neat interactive and up to date one! -- I would never make the jump but I am definitely not Einstein!

*yawn* it made me want to take a nap. this was not a FUN teaser.

I SO did not get this one until I read the comments. I guess it's obvious I slept through Chemistry class, huh? LOL Good teaser & very original. Way to go!

I think it is cofuzziling

that was a confusing riddle but it was fun.

I think you should put a hint! Other than that, it was a very creative teaser.

If the above comments are confusing, it is because the teaser has finally been corrected.

The elements (104-112) have been removed as they have been known for 10 years and are not alphabetically first, a missing element was added to the list, and the answer was corrected.

Suggested hint: Elementary, my dear Watson. Elementary, my dear teaser fan!

While I actually did solve this, I think the (somewhat) arbitrary nature of the teaser and the lack of any hint don't make this fun. The only reason I got it is because I've seen this series before.
