  1. Super-Heavy Elements Element 110-118 are known as The Super-Heavy Elements Kris Fisher 5-6

  2. Darmstadtium Ds Made in November of 1994 in Darmstadt, Germany by Armbruster and Münzenber Atomic Number 110. 110 protons, 160 neutrons and 110 electrons in a neutral atom giving it an atomic weight of 270. Half-life of 0.00017 seconds. Made by firing nickel atoms at lead. Named for where it was made Darmstadt Kris Fisher 5-6

  3. This is the symbol on the periodic table. Since only a few atoms of this element were made, it is nearly impossible to have a photo of it. Kris Fisher 5-6

  4. I could not find a picture of Gottfried Münzenber This is Armbruster Kris Fisher 5-6

  5. RoentgeniumRg Also made by in Darmstadt, Germany by Armbruster and Münzenber in December of 1994 Atomic Number 111. 111 protons, 170 neutrons and 111 electrons in a neutral atom giving it an atomic weight of 281. Half-life of 26 seconds which helped theorize the “island of stability” near Atomic number 114. Made by firing nickel at bismuth Kris Fisher 5-6

  6. It is named for Wilhelm Conrad Röentgen as shown on the right. Kris Fisher 5-6

  7. CoperniciumCn Same creators and location. Made in February, 1996. Atomic Number 112. 112 protons, 173 neutrons and 112 electrons in a neutral atom giving it an atomic weight of 285. Half-life of 30 seconds, continuing the theory. Named for NicolausCopernicus. Made by firing zinc atoms at lead atoms Kris Fisher 5-6

  8. Named for NicolausCopernicus a well know Renaissance mathematician and astronomer. Kris Fisher 5-6

  9. UnuntriumUut Made in February, 2004 at The Joint Institute for Nuclear Research  in Dubna, Russia by scientists from around the world Atomic Number 113. 113 protons, 173 neutrons and 113 electrons in a neutral atom giving it an atomic weight of 286. It has a Half-life of about 20 seconds. Made by firing calcium atoms at americium atoms. Kris Fisher 5-6

  10. The Joint Institute for Nuclear Research emblem Kris Fisher 5-6

  11. Ununoctium Made in July of 2006 at The Joint Institute for Nuclear Research  in Dubna, Russia by scientists from around the world. This is currently an element used only for scientific research. It is the heaviest element ever seen in a laboratory. It only lasted for 1,000th of a second and was said to have been produced in 1999 by the Lawrence Berkeley National Laboratory however this claim was proved false after an investigation. It was made by firing calcium at californium Kris Fisher 5-6
