Homework Help: science - periodic table

Posted by manny on Tuesday, September 4, 2007 at 4:12pm.

Some elements are missing, and others have no name but have an atomic number. (116) When will the table ever be complete? How do we know that it's not already complete?

The table will be complete when scientists stop making new elements. It is complete now for elements that occur naturally
