Periodiek système

Et periodiek système van d'elementn is e geordende rangschikkienge van alle chemische elementn. De ountdekkienge van die ordenienge wor toegeschreevn an Dmitri Mendeleev, oewel da der al iddere versies bestoegn die lik vôorlôpers anzien kunn wordn. Mendeleev ze tabelle bestoegt d'r in da d'elementen die in dezelste groep stoegen gelykoardige eigenschappn aan, of m.a.w. da d'r e periodieke trend awezig was. Dankzy zyn rangschikkienge kost Mendeleev eigenschappn vôorspelln van elementen die nog nie ountdekt woarn.
