  • The periodic table could soon welcome a new elementit's currently unnamed but known

  • as the super heavy element 117. You might want to sit downit's time for a science

  • lesson.

  • "It's really exciting because it's the generation of new matter. It's almost like a chill goes

  • up your spine, it's like wow, something new, something really exciting. It's almost akin

  • to a Nobel Prize." (Via YouTube / Periodic Videos)

  • Element 117 is synthetic and was first created in small amounts back in 2010. A little background

  • any element with an atomic number higher than uranium's 92 is unstable. Those higher

  • elements undergo a decay process, unlike those that naturally occur. (Via Wikimedia Commons

  • In order to create element 117, researchers have to use accelerator technologies to cause

  • specific atoms to fuse together.

  • ​"Calcium ions are accelerated to high velocity toward the target of Berkelium atoms... only

  • one of billions fuse with target to create element 117." (Via Lawrence Livermore National

  • Laboratory)

  • And that is how the super heavy element is created. But why should we care about the

  • elusive 117?

  • To put it plainly, one researcher said, "The successful experiments on element 117 are

  • an important step on the path to the production and detection of elements situated on the

  • 'island of stability' of super-heavy elements." (Via E Science News)

  • As a writer for LiveScience puts it, "If such an 'island' exists, the elements in this theoretical

  • region of the periodic table could be extremely long-livedcapable of existing for longer

  • than nanosecondswhich scientists could then develop for untold practical uses."

  • So basically, at this point, the implications from the discovery of 117 are endless. Its

  • status as an element will soon be decided by a committee from the International Union

  • of Pure and Applied Chemistry.
