What is the basic difference in approach between Mendeleev's Periodic Law and the Modern Periodic Law?

Options

  1. AMendeleev's law is based on atomic number, while the Modern Periodic Law is based on atomic mass.
  2. BMendeleev's law emphasises the periodicity of properties, while the Modern Periodic Law emphasises the arrange
  3. CMendeleev's law includes all known elements, while the Modern Periodic Law excludes elements beyond a certain
  4. DMendeleev’s Periodic Law states that the physical and chemical properties of elements are periodic functions o

Correct answer

D. Mendeleev’s Periodic Law states that the physical and chemical properties of elements are periodic functions o

Step-by-step solution

Correct Option is : (D) Mendeleev’s Periodic Law states that the physical and chemical properties of elements are periodic functions of their atomic weights. On the other hand, the Modern Periodic Law states that the physical and chemical properties of elements are periodic functions of their atomic numbers.
