A)electron configuration
B)atomic mass
C)density
D)boiling point
E)oxide formula

Question

Quizplus · Accepted Answer

Mendeleev's periodic table was based on atomic mass, and he could only predict the relative positioning of yet-to-be-discovered elements based on their position in the table. Mendeleev did not have knowledge of electron configurations, so he could not have predicted them for unknown elements. However, he did predict elemental properties like atomic mass, density, boiling point, and oxide formulas based on the trends observed in known elements.
