The Periodic Table of Elements - Periodic Chart

Chemistry is the section of science that studies the characteristics of substances and their reactions when they are mixed with each other. Basically, chemistry is the study of matter and the composition, structure and reactions of matter. So what is matter? Everything on Earth and in our universe is made up of matter - anything you can see, touch or smell is considered matter.

Matter comes in three different main states: gases, liquids and solids. There's also a fourth state, plasma, but it only exists at very high temperatures. Molecules in a plasma state don't always behave the same. Speaking of molecules... atoms and molecules are what make matter possible. They're what every material in the universe is made of.

Confused? Because there are so many elements (a substance that cannot be broken down any further) and there's the chance of more being discovered, they've been organized into a table. The Periodic Table of Elements or Periodic Chart as it's also known as, is based on atomic numbers and electron configuration. There are 109 elements that make up the Periodic Table of Elements so far. Element names are abbreviated. Most of the time the abbreviations make sense (like C for Carbon) but not always (like Na for Sodium.) There are four elements that make up 99 percent of living organisms. They are: hydrogen (H), oxygen (O), nitrogen (N) and carbon (C).

The Periodic Table of Elements is arranged in rows called periods. Columns in the chart are grouped together by similar properties like gases, metals and earth. The number in each box is the number of atoms and the letters are the abbreviation for the symbol. Click here to check out the Period Table of Elements and more information on the elements.

Today, several states had thousands of women joining together to fight against Trump. Celebrities like Madonna, Ariana Grande, and Miley Cirus showed up, some gave speeches, women shouted and raised their signs. Will Trump budge? What do you think? Should women be able to have abortion? Should Trump cut funds of women?

I think it loads faster, compiles faster, and is just overall smoother... The only thing that the Steam version has that this one does not is access to the 'workshop,' in which you can easily share and play other people's games. Ah, cool! X3 I'll pass on your advice to my friend so someone may benefit from it, as I don't use the application anymore. Thanks ^-^

He's the leader of our country, whether we like it or not, and we need to help him, as our government is based on the people. When you wish for him to fail, you're practically wishing for the country to fall... which isn't a good thing for the citizens o.o

I've made several top-down and platformer games, as well as one 3D game. I never got too far with my 3D game, but I have the basic movement down. Right now, I'm working on a top-down survival shooter game! I've done a bit of experimenting with GameMaker Studio, but was too lazy to learn the coding and dropped it :P My friend is learning how to actually USE it though. He always makes fun of me for it, lol. Do you use it through Steam or found the program and downloaded it?
