How did the concept of atomic number contribute to the synthesis of new elements in the laboratory?
30
The concept of atomic number was used to name newly synthesized elements.
The concept of atomic number discouraged scientists from attempting to synthesize new elements.
The concept of atomic number allowed scientists to predict the properties of undiscovered elements, guiding their synthesis.
