• Dmitri Mendeleev

What was the basis for Mendeleev's organization of elements in the periodic table?

• Atomic mass and chemical properties

• Number of protons and atomic weight

• Number of neutrons and electron configuration

• Number of electrons and reactivity

How are elements arranged in Mendeleev's periodic table?

• In order of increasing atomic weight and groups elements with similar properties together

• In random order and groups elements with opposite properties together

• In order of decreasing atomic number and groups elements with similar properties together

• In order of increasing atomic number and groups elements with similar properties together

What are the advantages of Mendeleev's periodic table?

• Arrangement of elements based on atomic weight

• Prediction of undiscovered elements' properties and organization based on properties

• Color-coding of elements for easy identification

• Inclusion of radioactive elements in the table

How did Mendeleev's periodic table fail to account for some elements?

• It included too many elements

• It did not explain the position of isotopes.

• It failed to organize the elements by atomic mass

• It did not show the relationship between elements

Why is the organization of elements in Mendeleev's periodic table considered a limitation?

• It is too organized

• It includes too many elements

• It does not accurately represent the electronic configuration of elements.

• It is not based on scientific principles

What is the impact of Mendeleev's periodic table on the development of modern chemistry?

• It led to the discovery of new elements

• It provided a framework for understanding the periodic trends of elements

• It helped in classifying elements based on their color

• It organized elements based on their atomic weight

Which of the following is a limitation of Mendeleev's periodic table?
