Free online mock test for Periodic Properties and Variations of Properties (ICSE Class 10 Chemistry) — 20 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
What to expect: This mock test covers key concepts from the Periodic Properties and Variations of Properties chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.Why does the oxidizing power of elements increase on moving from left to right along a period in the periodic table?
- A.Electronegativity and non-metallic character increase, enhancing electron gain.
- B.Atomic radius decreases, making it harder to lose electrons.
- C.Metallic character increases, reducing the tendency to gain electrons.
- D.Ionization energy decreases, making electron gain easier.
-
2.If an element A belongs to period 3 and Group II then it will have :
- A.3 shells and 2 valence electrons
- B.2 shells and 3 valence electrons
- C.3 shells and 3 valence electrons
- D.2 shells and 2 valence electrons
-
3.Newland law of octave arranged elements in increasing order of?
- A.atomic radius
- B.atomic number
- C.atomic structure
- D.atomic masses
-
4.Assertion: Noble gases are placed in different group in periodic table. Reason: Noble gases are inert in nature. (a) Assertion and reason both are correct statements and reason is the correct explanation of the assertion. (b) Assertion is true, but reason is false. (c) Assertion and reason both are correct statements, but reason is not the correct explanation of the assertion. (d) Assertion is false, but reason is true
- a.Assertion and reason both are correct statements and reason is the correct explanation of the assertion.
- b.Assertion is true, but reason is false.
- c.Assertion and reason both are correct statements, but reason is not the correct explanation of the assertion.
- d.Assertion is false, but reason is true
-
5.Name three elements present in the periodic table which do not undergo any chemical reaction to form compounds. Identify the group in which these elements are present and select the correct reason for their behavior:
- A.Helium, neon, argon; Group 18; they have a complete octet, resulting in a stable electronic configuration.
- B.Lithium, sodium, potassium; Group 1; they lose one electron easily to achieve stability.
- C.Fluorine, chlorine, bromine; Group 17; they gain one electron to complete their octet.
- D.Carbon, silicon, germanium; Group 14; they share electrons to form covalent bonds.
