The Periodic Table (update)

4 elements officially "recognised" by the scientific community (there is now enough evidence, supported by at least 2 separate groups of scientists, to support their existence ...!).  This completes row 7 of the periodic table.  We are now up to 118 elements ....and counting......Although some periodic tables online show elements 119, 120 and on......These haven't been "proven" yet.

Many of the most recent elements have been "made" in labs and never found naturally on Earth.
