118 - as of yesterday. They found 118 as a cooperation between the US and Russia. It is chemically a noble gas, like radon. It is radioactive and has a half-life in the microsecond range.

About 118, but there might be more that have not yet been created.
Originally I posted "about 114" which was what I remembered from school days. I did a scan and found I was out of date!
Many of these later discovered elements are short lived and can only be created in accelerators. i.e colliding other nuclei together.
I don't know if there is limit to how many new ones could be created, if so it may be an economic limit - how many billions of $ is it worth to create a new element for a few picoseconds ?

The current standard table contains 117 confirmed elements as of October 16, 2006(while element 118 has been synthesized, element 117 has not)

potentially, an infinite number, in reality, a probable maximum of around 130 due to the inherent instablilty of of the nucleus
