Question

Mendeleev's strategy for classifying elements was modeled on a(n) ___________.

a) chemical theory
b) structural framework
c) elemental principle
d) card game

Answer 1

Mendeleev's strategy for classifying elements was modeled on a periodic pattern. He organized the elements based on their increasing atomic mass and noticed that certain similarities in chemical behavior repeated at regular intervals. This led him to create the periodic table of elements, where elements with similar properties are grouped together.
