The MOST recently discovered element was atomic number 118. It is being temporarily called 'ununoctium'. As to WHEN it was discovered... that's a little more complicated.
A team of element-makers at Lawrence Berkeley lab claimed to have made it in 1999, but when nobody could reproduce the find with the lab's methods (even the original lab), their finding was discredited.
In Spring of 2002 (it took four months) the Joint Institude of Nuclear Research in Dubna claimed to have produced an atom of ununoctium. This was confirmed by Dubna and the Berkeley lab when each of them produced another atom in 2005.
The average lifespan of these three atoms was just under a thousandth of a second. So don't expect any accumulation of the stuff!
