Elements de periodic of table!

    
      Looks complicated right? Well not if you really learn about it. Now memorizing it.. that would be difficult. That right there, if you didn't know, is the PERIODIC TABLE OF ELEMENTS! Since it's important it deserves to be in caps! So basically it's a table...of elements...and it's periodical. It organizes all elements known to the world. Well I think we should start from the very beginning with a guy named Dmitri Mandellev:

     Why are all old scientists names complicated? UGH! Anyway, he was born in 1834 and was the youngest of 17 FREAKING CHILDREN! GOODNESS! In the 1860s, the periodic table was born! Wow! He had to be really smart to develop a whole table of elements and how they fit together. Okay, let's move on to the actual table and how it works. So, the letters that look random are actually an abbreviation for the name of the element. The numbers on top of that, list the number of protons each element has. Below the letters, lists the atomic mass.

     Okay so now we're going to talk about how the elements are organized. They are organized into periods, groups, and colors. Periods move horizontally. They describe the number of electron shells each element has. That is the lines that electrons travel in. A whole horizontal line has the same number of electron shells.

     Next are groups which are organized vertically. All of the elements in one row have the same have ability to lose the same amount of electrons or gain some.

electron shells

     Isn't the periodic table colorful? Well there's a reason for that. Each color is a different category. Here are the catagories:

1. Alkali Metals
2. Alkaline Earth Metals
3. Trasition Metals
4. Poor metals :(
5. Semimetals
6. Non-Metals
7. Noble gases

    Oh and if you're wondering what the random elements are on the bottom, scientists just couldn't include them so they're all left out on the bottom D: Also, elements above 92, cannot appear in nature because they're way too unsteady and have to be created in a lab.
