Recent Periodic Table Quizzes

IB Chemistry HL: Mastering the Periodic Table

Questions: 9 | Attempts: 48 | Last updated: Nov 11, 2025

Sample Question
Describe the arrangement of elements in the periodic table in order of increasing atomic number.

The periodic table is organized by arranging elements in order of increasing mass number.

The periodic table is arranged solely based on the physical state of elements at room temperature.

Elements are arranged in the periodic table based on their decreasing atomic number from left to right.

Names and symbols of the elements are given in the Chemistry data booklet. The history of the periodic table will not be assessed. Periodic Table is arranged according to increasing atomic number and consists of horizontal rows called periods, and vertical columns called groups (or families). The arrangement is such that elements with similar chemical properties fall directly beneath each other in the same group.
