Ughhh My best friend just lost her favorite necklacess!! I just hate it when I lose jewelry! So, have you guys ever wonder what jewelry is made of? Well I am going to answer this question and lots of others of others with my science blog. How can science relate to jewelry you ask, well elements make up everything on earth and that includes jewelry. Platinum is one of the key elements that make jewelry but platinum is also one of the key "ingredients" to containers catalysts. Platinum was discovered by Julius Scaliger in 1735. Platinum has 78 protons in its nucleus and 78 electrons but it has 117 neutrons. Platinum is a transition metal which means it is both ductile and malleable, and can conduct electricity and heat.
My favorite color is neon green, so when I learned about this element green was always in my head. If you guessed that the element was green sorry but you are wrong, the element I studied is neon!!! Neon can be found in lightning and also used in some glow in the dark items but only in the red ones. Neon has 10 protons, neutrons and electrons. Neon was discovered in 1898 by Sir William Ramsay. Neon is a noble gas. Have any of you seen the movie called Back to the Future?? Well I sure have cause it was my cousins favorite movie (he loves science!) If you haven't there is this car that can take you to your past and in the movie it runs on plutonium which is our next element. Plutonium isn't only used in movies but its mostly used in bombs and neuclear reactors. It has 94 protons,150 neutrons and 94 electrons. It was discovered in 1940 by G.T Seaborg. The name comes from the dwarf planet, Pluto. Our next element is Thulium. It is mostly used in the power for portable x-ray machines and lasers. It was discovered by Per Theodore Cleve, from Sweden. It has 69 protons, 100 neutrons and 69 electrons. Thulium is named after Thule, an acient Roman name for a mythical coutry in the far north, maybe Scandenavia. Thulium is kinda rare since it is only found in small quantities. Click here! Click here! Click here! Click here! I'm a video!
Hey bloggers!!! This is my first blogg!!!! yay! I hope you like it! So guys do any of you have older siblings?? I do and there soo annoying!! Imagine having 17!!! Dmitri was the youngest of 17!! (why is he important?) He was the guy that made the periodic table. So the periodic table is this table that categorises by the elements based on the properties of their atoms. They are also organized by color into different categories. The color categories are: Alkali metals, alkaline earth metals, transition metals, poor metals, semi metals, nonmetals and noble gasses. Here is the periodic table to so you get an idea of what we're talking about! :) I luv these colors!!
So the atoms are organized in groups and periods. Elements with similar configurations of electrons are arranged in vertical columns called groups. Periods are sets that describe the # of electron shells the elements have. Hey guys do you see the number at the top of the abbreviation? That is the atomic number. No, an atomic number isn't a number that is atomic!Its the number of protons in the nucleus of each atom. Some atoms have to be made in a lab, in fact all the elements above 92 have to be made in a lab because they are too unstable!Here are some links so you can find out more about the periodic table! http://www.chemicool.com/%20http://periodic.lanl.gov/about.shtml (This one is the song http://www.youtube.com/watch?v=uJGrwWOWt3Q&feature=related) Bye! talk to ya'll later!! ;) This the atom! :)
Hey people of the world, its Rylie blog! Have you guys been listening to the news? No? Well on September 11 of this year it was the 10 anniversery of 4 planes being hijacked and intentionally crashed into the twin towers and 1 into the pentagon.Within 2 hours the 2 towers had fallen down and they were both in flames. There were 4 planes hijacked by 11 terrorists! America did exactly opposite from what the terrorists wanted, every one was there for one another no matter what race you were everyone felt each others pain. The really amazing thing that happened was the passengers on the 4th plane realized what was happening and fighted the terrorists so that the plane wouldn't crash into the white house or the capitol building. They risked their lives to save others! Imagine what bave people they were! To remember them their are walls infront of where their plane landed that has everyones name carved into them. The event not only struck America but it was a warning to the world that anything can happen and you may not expect it. This attack of course changed America, and the families of all the people who died. I hope that when America looks back and sees the brave people who wittnessed 9/11,they looks up to them! Also, remember the people who performed heroic acts!I think we should have a holiday in memory of 9/11 to really take time to reconize the terrible event and what the people went through. Thanks for listening!! bye! This is where the buildings once stood and is now Ground Zero, a memorial for all the people who died on September 11th 2001.
I luv these colors!!
