Oganesson
- 1. Hi. If you continue to read this , I dont know If you will be amazed by me or you will just ignore me.
- 2. I am not famous as Hydrogen. I am a harmful one. I am only used for research interest only.
- 3. My name is Oganesson. My name pronounced as oh-gan- ess-on. Named after the scientist Yuri Oganessian. I will show you his picture.
- 5. I am an element 118. Which means I have 118 proton,118 electron and 176 neutron.My Atomic weight is 294. My melting point,boiling point and density are still unknown.
- 6. My Element Classification is Non- metal. My Period Number is 7. My Group Number is 18 .My Group Name is Noble Gas
- 8. Do you really wanted to know me? Okay, lets proceed. I was discovered in 2002 by Russian scientists at the Joint Institute for Nuclear Research in Dubna, Russia.
- 9. Three years prior, in 1999, the team at the Lawrence Berkeley Labs in California published a paper announcing the discovery of element 118, but their results could not be replicated and the team retracted their paper.
- 10. The reaction was a fusion of element 20 with element 98: with Calcium ions were formed into a beam in a cyclotron (a particle accelerator) and fired at a target layer of californium oxide deposited on foil.
- 11. Bombardment lasted 2300 hours, accumulating a total dose of 2.5 x 1019 calcium ions. Two atoms of oganesson-294, which existed for 2.55 ms and 3.16 ms, were produced in March 2002.
- 12. Further experiments and analysis later confirmed this result and the discovery was verified by The International Union of Pure and Applied Chemistry (IUPAC) in 2015.
- 13. In October 9, 2006, the element was officially announced by the Dubna team and by the Lawrence Livermore National Laboratory team, who had been working with the Dubna scientists.
- 14. When I was born, I and other 6 elements was accepted by IUPAC ,namely:
- 15. We completed the seventh row of the periodic table.
- 16. Wait.I wanted to show you the Bohr Model of me. Its really awesome. 118 electrons are lined up.
- 17. My model is pretty cool. But my appearance and Characteristics may be the reason for you to dislike me.
- 18. I am harmful due to my radioactivity. I am a synthetic radioactive metal and has only been produced in minute amounts. My uses? I am only used for research interest only.
- 19. I am partly like myself. But maybe if scientist found a positive and very useful purpose for me it will truly makes me happy.
