iGCSE Chemistry Multiple Choice (Extended) : 8.1 Arrangement of elements: Exam Style Questions Paper 2

iGCSE Chemistry MCQ (Extended) Paper 2 - All Chapters
Question

Which statements describe the Periodic Table?

1 The elements are arranged in order of their nucleon number.
2 The elements are arranged in order of their proton number.
3 It is used to predict the properties of elements.

A) 1 and 3
B) 1 only
C) 2 and 3
D) 2 only

▶️ Answer/Explanation
Solution

Ans: C

The Periodic Table arranges elements by increasing atomic (proton) number (statement 2 is correct, 1 is wrong). The periodic arrangement allows prediction of element properties based on their position (statement 3 is correct). Therefore, option C (2 and 3) is correct. Nucleon number (mass number) isn’t the basis for the periodic arrangement, as isotopes would disrupt the periodic trends if it were.
