Periodic BOREDOM!

If you're going by the above periodic table, you are so definitely screwed for chemistry.

Today we're going to make this short and sweet since nobody cares about history!
So, Gods know how many years ago, people thought the world was made up of four elements: Earth, Air, Fire, and Water. Of course, these old ancient people were WRONG. A fair number of elements were discovered in the 1800's, but nothing notable until Mr. Mendeleev came along, and created the elegant Periodic Table of Elements.



Jargon aside, this table organized elements so that common characteristics would reappear periodically. With rows being periods and columns being families, each family would have similar characteristics because they are separated by a period. Make sense? Well figure it out. This is a history lesson.
Mendeleev's table was in fact, so elegant, that it predicted and left gaps for elements that had yet to be discovered. Ever since, it has been infallible. And ever since, over 100 elements have been discovered and named. All we have to do is appreciate this. Oh and know all this since it'll be on the test. The below image also won't help you with that portion of the test.
