= Element Name= By: Your First Names ONLY!


 * Atomic Number:** Place your atomic number here.


 * Protons:** Using the atomic number figure out the number of protons. Remember that the atomic number equals the number of protons.


 * Electrons:** Using the atomic number figure out the number of electrons. Remember that neutral atoms have the same number of protons and electrons. For this assignment assume atoms of your element are neutral. 


 * Neutrons:** Using the atomic number and average atomic mass figure out the number of neutrons in the most common isotope. Remember to calculate the number of neutrons in the most common isotope you round the average atomic mas to the nearest whole number and subtract the atomic number. 


 * Average Atomic Mass:** Record the average atomic mass. Your units should be in atomic mass units (amu).


 * Isotopes:** List the isotopes for your element. [|WebElements] is a great place to find this information. Look for the "Isotopes" link on the right side of your element's page.


 * Discovery:** How was the element discovered? Who discovered it? If you find a site saying "this element has been known since ancient times" that is okay to note for discovery. [|WebElements] is a great place to find this information. Look for the "History" link on the right side of your element's page.
 * Name:** How was the element named? Was it named after a person or place? Note any information you find about its atomic symbol and why that symbol was chosen. [|The Origins of Element Names] and the History section for your element on [|WebElements] are great places to find this information.


 * Uses:** How is your element used? Look under "Uses" for your element on [|WebElements] and listen to what scientists at the University of Nottingham have to say about your element on the [|Periodic Table of Videos].


 * Interesting Facts**: What are some interesting facts you found out about your element?


 * Video:** Hopefully you already used the [|Periodic Table of Videos] to find the video about your element. Embed your element's video in this page using the video tool (the one that looks like a TV) so that others may watch it too. Hint: To get the Embed code you'll need to click the YouTube logo once the video is playing. This will take you to the YouTube page for the video.
