What do you think a revised periodic table might look like?
QUESTION 9
Mendeleev’s periodic table is not the same periodic table we use today. Compare and contrast Mendeleev’s table and the modern periodic table. Use the text and Figures 2 and 7 to explain two similarities and two differences of both organizational systems.

A revised periodic table might include newly discovered elements and use a different layout, such as a spiral or an expanded table that places the lanthanides and actinides within the main body. It would likely still organize elements by atomic number and recurring chemical properties.
Two similarities: Both tables organize elements systematically to show repeating patterns in their properties, and both group elements with similar chemical properties together.

Two differences: Mendeleev arranged elements mainly by increasing atomic mass, while the modern table arranges them by increasing atomic number. Mendeleev’s table left gaps for undiscovered elements, while the modern table includes many elements discovered since his time, including the noble gases.

The referenced Figures 2 and 7 are not visible in this image, so these comparisons are based on the established features of the two tables.
