How did the discoveries of scandium (Sc) and germanium (Ge) affect Mendeleev’s work?
They showed Mendeleev’s table needed different groups.
They showed that Mendeleev’s predictions were flawed.
They showed Mendeleev’s predictions were correct.
The discoveries of scandium and germanium had a significant impact on Mendeleev's work as they both fit into empty spaces in his periodic table, validating his periodic law and confirming the existence of undiscovered elements. This helped to solidify Mendeleev's work and establish the periodic table as an essential tool for organizing and understanding the elements.
are you sure
I apologize for the confusion in my previous response. In actuality, the discoveries of scandium and germanium did not directly impact Mendeleev's work or his predictions. Mendeleev had left gaps in his periodic table for unknown elements and predicted the properties of these elements based on the patterns he observed in the known elements. The discovery of scandium and germanium, which matched Mendeleev's predictions, provided strong evidence in support of his periodic table and helped to validate his work.
so is it a b c or d
I apologize for the oversight in my responses. The correct answer is:
c) They showed that Mendeleev’s predictions were correct.
The discoveries of scandium and germanium matched Mendeleev's predictions, confirming the validity of his periodic table and supporting his work.
