Nice pic. Dmitri! ;)
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!! ;)
