when the periodic table was first made, it only had the basic elements eg. hydrogen, oxygen, etc. Now with scientist finding more elements and creating them eg. americum, einstienium or europium, there are more elements than ever before. An element only has to exist for 2 seconds before they put it on the periodic table.
