The Periodic Table: Writing
The Periodic Table
Did you know that are currently 118 elements in the Periodic Table starting from Hydrogen all the way to Ununoctium. The Periodic Table is a large group of chemical elements that are arranged by their atomic number and their recurring chemical properties.In the mid 1800s, Dmitri Mendeleev created his own version of the periodic table when he created a card game with the elements where he would arrange them by their atomic number, atomic mass, & chemical properties. Dmitri Mendeleev was a Russian chemist & an inventor.

Element Name: Hydrogen
Atomic Number: 1
Chemical Symbol: H
Atomic Mass: 1.0
Melting Point: 434.5F (-259.1C)
Boiling Point: -252.762 C
Density: The Density matters on what the temperature and the pressure is.
Is it a Metal, Metalloid, or Nonmetal? 1. Nonmetal
Is it a solid, liquid, or gas? 2. Hydrogen is a Gas
What period is it in? 3. It is in Period 1
What family or group is it in? 4. It is in Group 1
By who? In what year? and where was it discovered? 5. It was discovered in 1766 by Henry Cavendish in London, England.
My Description on how Hydrogen is used in the modern world. (5-8 sentences)
Hydrogen is the lightest element in the periodic table. It has the chemical symbol of H and it has the atomic number 1. Even though the elements in Group 1 are alkaline metals, the list of alkaline metals start from Lithium down. So Hydrogen is not an alkaline metal, it’s a non-metal specifically a gas. Hydrogen as water is important for Human life. Hydrogen gas was used in lighter-than-air-balloons for transportation, but it was far too dangerous because of the fire risk.

Communication
Communication
The history of Communication has since then evolved from Cavemen throwing rocks at each other to posting a new tweet on Twitter. There are so many ways to communicate with your friends and family and yet some many to be created, but I think the best way to communicate with someone is Facebook.
First of all, one reason why Facebook is the best way to communicate with someone because you can communicate with multiple people at once. On Facebook, you can choose to like or dislike a comment if you find it funny, surprising, or mean, racist, and just plain out stupid. Also, you can meet new people by friending them and then you could learn everything about them by checking their profile. Overall, Facebook is a good fast working site where you could talk to all of your friends in a matter of seconds.
There are many options to communicate with that have similar features, but Facebook is different. On Twitter, when you are talking to your friend you see people who you don't know sending messages to you, while on Facebook you'll only see people that you know. When you text it takes atleast a minute to send a message to your friend, on facebook it takes a minute to talk to 5 friends. Also, on Facebook you can post pictures when on texting you can't, even if somehow you do find a way to put a picture when texting it takes like 3 minutes.
You may think Facebook is a bad sight due to all of the creepers on the internet. Someone can easily check up your profile and learn every single detail about you. Then that someone might find out where you and try to track you down and once he finds you he might molest you or possibly kill you! The internet is sometimes a bad place where creepers lurk and may say that creepers are mostly on facebook.
There are many ways to communicate with someone, but I think the best way is Facebook. Every reasonable person would agree that facebook is a good website for people to interact with their friends and family. I suggest you make a Facebook profile and meet new people, but not the creepers.
