Table Manners!

Sup! So when you're little your parents always tell you, 'Mind your manners little (y/n)!'. Table anners are important, but let's talk about a different type of table. The Periodic Table.

On the chart above ^^^^^^ you see colorful squares right? Well those squares respresent elements. What's that? You don't know what elements are? Hmm.... ok. Breathe in. You feel that stuff that you are are breathing (p.s. you should probably breathe out now...)? Well it's called oxygen. It's an element! Does it make more sense now? No? Let's try again. So hopefully you drink water. Well in all of my earlier posts I've mentioned water H2O the wonderful liquid in which we drink. Water is made of two hydrogen and one oxygen. Oxygen and Hydrogen are both elements.





This is Hydrogn's 'block' if you will. We'll start at the top. You see that 1 in the corner? It represents the atomic number, or number of protons/electrons. Now let's move down to the H. The H is what they call the element symbol. Usually, it consists of one capital letter and one lowercase letter. These letters, besides the colors, are the most noticable thing on the Periodic Table, other than the ever so pretty colors. In this case the 'H' is the first letter of the element, hydrogen. That, however, isn't always the case. Sodium, or salt, has the element symbol of Na. Weird huh? On to mass. The atomic mass is the number of protons and neutrons in the element. Elements on the periodic table are organized into rows called periods and columns called groups.

The elements on the right side are non-metals. While the elements on the left are metals. The division between the two aren't anywhere neat the same. It's more like 2/3 are metals and 1/3 are non-metals. All elements with an atomic number above the number 98 have to be made in labs though. They can kill people if they aren't... that and it involves human interaction the get them to gain more electron shells. Weird huh?

So who created the Periodic Table? 1869; Dmitri Mendeleev. AKA That guy down there 

 

So believe it or not, Mendeleev was actually considered cute when he was in high school. You could cay he was the Justin Bieber of the 19th century. Any who, this man designed the periodic table and left space for elements to be discovered long after he kicked the bucket. Was he a genius or what?

Was that enough? If you need a recap here is a song! Hope you liked me post! xx-G

P.S. I know it was short...
