0 1 This question is about the periodic table. In the 19th century, some scientists tried to classify the elements by arranging them in order of their atomic weights. Figure 1 shows the periodic table Mendeleev produced in 1869. His periodic table was more widely accepted than previous versions . 1 The atomic weight of tellurium (Te) is 128 and that of iodine (I) is 127 Why did Mendeleev reverse the order of these two elements? . 2 Mendeleev left spaces marked with an asterisk * He left...
