Sample Kerala SSLC Chemistry Practice Questions

Try these sample questions to review concepts for the Kerala SSLC Chemistry exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1The modern periodic law states that the properties of elements are a periodic function of their:
A.Atomic mass
B.Mass number
C.Atomic number
D.Neutron number
Explanation: Modern periodic law (Moseley): properties depend on atomic number (number of protons), not atomic mass.
2Elements in the same group of the periodic table have the same:
A.Number of electron shells
B.Number of valence electrons
C.Atomic mass
D.Number of neutrons
Explanation: A group shares the same number of valence electrons, which drives similar chemical properties.
3The electronic configuration of sodium (Z = 11) is:
A.2, 8, 1
B.2, 7, 2
C.2, 8, 2
D.2, 9
Explanation: Sodium has 11 electrons: 2 in K, 8 in L, and 1 in M giving 2, 8, 1.
4Across a period from left to right, atomic size generally:
A.Increases
B.Decreases
C.Remains constant
D.First decreases then increases sharply
Explanation: Nuclear charge increases while shells stay the same, so atomic radius decreases across a period.
5Which element has the electronic configuration 2, 8, 8?
A.Argon
B.Chlorine
C.Potassium
D.Calcium
Explanation: 2 + 8 + 8 = 18 electrons, which is argon (Z = 18), a noble gas.
6Down a group, ionisation energy generally:
A.Increases
B.Decreases
C.Remains the same
D.Becomes zero
Explanation: Atomic size increases down a group, so the outermost electron is less tightly held and ionisation energy decreases.
7An element X has atomic number 17. Its valency is most likely:
A.1
B.2
C.3
D.7
Explanation: Z = 17 gives configuration 2, 8, 7; it needs 1 electron to complete an octet, so valency 1 (halogen).
8Which statement about noble gases is correct?
A.They have incomplete outer shells
B.They are highly reactive metals
C.They have stable complete outer shells
D.They form ionic compounds readily with alkali metals
Explanation: Noble gases have complete outer shells (He: 2; others: 8) and are chemically inert under ordinary conditions.
9Metallic character of elements across a period generally:
A.Increases
B.Decreases
C.Remains constant
D.Becomes maximum at the noble gases
Explanation: From left to right, tendency to lose electrons decreases, so metallic character decreases.
10The maximum number of electrons that can occupy the M shell (n = 3) is:
A.2
B.8
C.18
D.32
Explanation: Shell capacity is 2n squared. For n = 3: 2 times 9 = 18 electrons.

About the Kerala SSLC Chemistry Exam

Kerala SSLC Chemistry covers Class 10 secondary chemistry under Kerala Pareeksha Bhavan with SCERT Kerala syllabus support. Content prioritises SCERT Basic Science Chemistry chapters: Periodic Table and Electronic Configuration; Mole Concept; Rate of Chemical Reactions and Chemical Equilibrium; Reactivity Series and Electrochemistry; Production of Metals; Nomenclature of Organic Compounds; Chemical Reactions of Organic Compounds; and Chemistry for Human Progress as notified for the year. Official assessment is mixed TE (~40) + CE (~10) for about 50 marks total, with theory typically about 1.5 hours — not multiple choice alone. English and Malayalam media are commonly available; SCERT 2026 model papers exist on scert.kerala.gov.in. This free English MCQ bank builds concept and calculation fluency (including mole and n-factor style numericals) before students practise official model papers and CE/lab skills using resources from SCERT Kerala, Pareeksha Bhavan, and the Directorate of General Education.

Exam sponsor: Kerala Pareeksha Bhavan / Directorate of General Education, Government of Kerala (syllabus support: SCERT Kerala). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Official Kerala SSLC Chemistry assesses Class 10 SCERT Chemistry through a theory paper lasting about 1.5 hours (as notified), typically with objective-type questions plus short and long answer sections, plus Continuous Evaluation (CE) through the school. Public reporting commonly describes about TE 40 + CE 10 (total ~50). Confirm the current scheme and notification for section weights and internal choice. English and Malayalam media are commonly available. This 100-question bank is an English-language MCQ study adaptation of that written syllabus — it does not fully simulate the official multi-component TE/CE format or Malayalam-medium papers.

Time Limit

Typically about 1.5 hours for the official SSLC Chemistry theory paper as notified on the Pareeksha Bhavan / SSLC timetable. CE components are scheduled separately through the school.

Passing Score

Pass/promotion criteria follow Pareeksha Bhavan grading notifications; candidates typically need about a D+ band (~30% aggregate of TE+CE as applicable) and about ~30% in theory (TE). Confirm the current circular rather than unofficial fixed percentages.

Exam / Certification Fees

Included in the SSLC examination fee schedule paid through the school (or as notified for private/improvement candidates). Exact rupee amounts vary by year and candidate category; check the latest fee notification from Pareeksha Bhavan / Directorate of General Education rather than unofficial fixed quotes.

Exam sponsor website

Fees, eligibility, and exam policies can change. Confirm them with the exam sponsor before applying or paying.

Kerala SSLC Chemistry: Suggested Study Strategy

1Drill mole–mass–particle conversions, molar volume at STP, and n-factor/equivalent-style numericals with units every day — calculation fluency scores heavily on SSLC Chemistry papers.
2Practise writing full stepwise solutions for stoichiometry, electrolysis product prediction, and Le Chatelier equilibrium shifts — official TE papers reward clear working beyond MCQ recognition.
3For organic, master functional-group suffixes (–ane, –ene, –yne, –ol, –al, –one, –oic acid) and core reactions (addition, substitution, esterification, saponification) rather than only name lists.
4Link the reactivity series to displacement, corrosion, and metal extraction methods so the same order of metals unlocks multiple chapters.
5After MCQ concept checks, solve SCERT 2026 Chemistry model papers and complete CE/lab evidence on schedule through your school.
