Which of the following is true about Mendeleev's Periodic Table?
- A. Systematic study of elements
- B. Prediction of new elements
- C. correction of doubtful atomic weights
- D. All of the above
Step-by-step solution
Mendeleev's periodic table was a systematic study of elements based on atomic weights. It also predicted the existence and properties of undiscovered elements (e.g., gallium, germanium, scandium), and corrected doubtful atomic weights (e.g., beryllium, indium) to fit the periodic trends.
