This puzzle follows from the Purple Periodic Puzzle (these puzzles are solved individually).

Another strange periodic table has appeared and it's hiding a secret word.

Can you find out what's strange about this green periodic table and find the answer?

The wrong elements

seem to be switched in pairs:

So what do we do with this?

The atomic numbers here don't have any zeroes, and there's a fairly even distribution of digits - all of the nonzero digits appear at least once.

We can choose one of the elements from each pair, along with its new atomic number, to get all the digits from 1-9 once:

3=V / 4=O / 67=Si / 12=La / 89=Er / 5=I

Sorting these new letters from 1-9, we get LAVOISIER, an early chemist who was one of the first to attempt to list the chemical elements.

    $\begingroup$ Great job! Of course this is the right answer, but I noticed there seems to be a small error in the image. Er should go to Ac and Ho to Si. $\endgroup$ – DenverCoder1 Mar 4 at 23:07
