Mendeleev arranged elements in order of:

  1. Atomic number
  2. Density
  3. Atomic radius
  4. Atomic mass
Show answer and solution

Correct answer: D. Atomic mass

1. Mendeleev's periodic table came in 1869. 2. He used increasing atomic masses for the order. 3. The modern table later switched to atomic number after Moseley. 4. So Mendeleev used atomic mass. _Source: Selina Concise Chemistry ICSE Class 9, Ch 5 'The Periodic Table'_
