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'_

How many groups does the modern periodic table contain?

  1. 18
  2. 8
  3. 16
  4. 7
Show answer and solution

Correct answer: A. 18

1. The modern table has 18 vertical columns. 2. Each column is called a group. 3. Old Mendeleev tables had only 8 groups. 4. So the modern count is 18. _Source: Selina Concise Chemistry ICSE Class 9, Ch 5 'The Periodic Table'_
