The thing is, with the newer elements they have to be discovered by one party, then verified by another. What tends to happen quite often is that one party will say "We found element 1XX" but they are unable to reproduce that finding. As a result, their discovery doesn't really count. The thing is, the party that "discovered" that element believe whole-heartedly that they found it. In reality, until the finding can be verified and repeated they technically haven't discovered anything.
