the construction of the periodic table has been facilitated by spectroscopy by helping to identify elements; also, the construction has been helped by electron configuration because elements with the same valence electron configuration have been placed in columns. the arrangement of the periodic table is by atomic number which has been proven to best so far by experimentation. scientist may discover a new element by conducting experiments. if this were to happen now the element would have to go through naming and the school would have to buy new periodic tables. one fairly recent example of a discovery like this is Copernicium(Ununbium). this element was discovered by Sigurd Hofman, Victor Ninov, and others, by firing zinc at a lead target in a heavy ion reactor. in may 2009 copernicium was officially recognized and it took it's place on the periodic table in group 12, block d.
