The Fifth Element.These brain teasers rely on your ability to recognize groups of common attributes. For each of these puzzles you'll need to figure out why the words or letters are grouped as they are. Sometimes you will be asked to pick the odd-one-out or to place a new word into the correct group.
You need not be a science wiz, so there's no need to fret,
Still not as easy as 1, 2, 3 or learning the alphabet.
The group of elements you see below are quite unique for sure,
Though this is true, I do tell you, there shouldn't be just four.
If you solve this without a hint, perhaps you have a gift,
But if you need, go ahead indeed, so that you find the fifth!
HintIn Junior High, our Periodic Table squeezed THREE details into each little box.
In the group, I only gave two.
AnswerThe fifth element is Barium (Ba).
Barium (Ba), Iron (Fe), Mercury (Hg), Polonium (Po), and Strontium (Sr), are the only 5 elements on the Periodic Table whose symbols, when reversed, give you a set of two consecutive letters in the alphabet: aB, eF, gH, oP, rS.
