Dobereiner, Newlands and Mendeleev 1 of 10 How did Dobereiner organise the periodic table? arranged elements into three groups depending on their chemical properties called triads 2 of 10 What order did Dobereiner arrange the elements? order of atomic mass 3 of 10 How did Newland's arrange his elements? into groups which had different properties 4 of 10 what did Newland's do with metals and non-metals? he mixed them up 5 of 10 what did Newland's not do? He did not leave any gaps for undiscovered elements 6 of 10 What did Mendeleev do first of all? arranged the 50 know elements into the periodic table with various gaps 7 of 10 How did Mendeleev arrange the elements? In order of atomic mass 8 of 10 why did Mendeleev leave gaps? so that he could keep elements with similar properties in the same vertical group 9 of 10 What did the gaps that Mendeleev left predict? the properties of undiscovered elements 10 of 10
