Was the periodic table always been set up the way it is today?
the periodic table is set up by atomic number, obviously. the atomic number is equal to the amount of protons, so the periodic table is set up by amount of proton order. During the time more than 100 versions of the periodic table were proposed. See the link bellow for some details; also the links of this...link.
