Guida verificata passo dopo passo1
Understand that the question is about the historical development of the periodic table, a fundamental tool in chemistry that organizes elements based on their properties.
Recall that John Dalton is known for atomic theory, Marie Curie for radioactivity, and Antoine Lavoisier for naming oxygen and hydrogen and establishing the law of conservation of mass.
Identify Dmitri Mendeleev as the scientist who arranged the elements into the periodic table based on increasing atomic mass and predicted properties of undiscovered elements.
Recognize that Mendeleev's arrangement laid the foundation for the modern periodic table, which is now organized by atomic number rather than atomic mass.
Conclude that Dmitri Mendeleev is credited with arranging the periodic table into its modern form.
