Question

What was the basis of Mendeleev’s classification of elements?

Answer 1

Basis of Mendeleev’s classification of elements:

• The atomic mass is the basis of the Mendeleev’s classification of elements.
• The elements are arranged in the increasing order of atomic masses and their properties.
• Mendeleev’s law states that “the properties of elements are periodic function of the atomic masses”.
• The elements are arranged in horizontal rows known as periods and vertical column known as groups.
• The elements in the vertical columns possess similar properties.
