these questions could be found on the academic portal, at the announcements.
1.Is the version of the Periodic Table we're using the ONLY version?
Ans: there should be more than 1 type of periodic table as maybe some people do not know how to speak, for instance, english, so it would come in many language, but maybe that is not the main point. there should be other ways of grouping the elements in the table. but maybe as years progresses, the periodic table might expand and who knows, maybe somebody great would again simplify the table? but again, there would be a lot more new elements that would be added into the periodic table and there might be chance that the table would not be simplified but instead, become larger?? :)
2.How do scientist in other parts of the world come to a common understanding about the elements?
Ans:wow! that is a very difficult question to answer. it seems that maybe scientist just find the elements by themselves and maybe get together to provide their findings? or maybe, one scientist tell other scientist as you/we cannot work alone.as the saying goes, no man is an island, so they discuss with each other and the message goes on and on....that is just what i think only. arghhh.can't find but this should be it.
