This puzzle follows from the Purple Periodic Puzzle and Green Periodic Puzzle (these puzzles are solved independently).
Yet another periodic table has been uncovered and hides a secret word.
Can you find out what's strange about this blue periodic table and find the answer?
Can you spot the 3 types of differences?
Both the letters that were altered and the letters they were changed into are important for finding the missing words.
The answer contains 11 letters, but it is not an element on the periodic table.
For each of 11 letters that were changed, take the original letter and the letter it was changed to, to get a new letter which is part of the solution.
