MATSEC Intermediate Matriculation Chemistry (IM 06) is a University of Malta MATSEC subject assessed under the 2026 syllabus (one written paper of 3 hours). Results use grades A–E (pass) or F; IM grade points contribute to the Matriculation Certificate (minimum 44 points). The 100 questions on this page are an English-language MCQ study adaptation, not an official MATSEC format simulation.

Sample MATSEC IM Chemistry Practice Questions

Try these sample questions to test your MATSEC IM Chemistry exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which particles are found in the nucleus of an atom according to the Bohr model?

A.Protons and neutrons only

B.Protons and electrons only

C.Neutrons and electrons only

D.Protons, neutrons and electrons

Explanation: The nucleus contains protons and neutrons (nucleons). Electrons occupy shells outside the nucleus.

2An atom of chlorine has proton number 17 and nucleon number 35. How many neutrons does it contain?

A.17

B.18

C.35

D.52

Explanation: Neutrons = nucleon (mass) number − proton (atomic) number = 35 − 17 = 18.

3Isotopes of the same element always have the same:

A.number of neutrons

B.nucleon number

C.number of protons

D.relative isotopic mass

Explanation: Isotopes are atoms of the same element: same proton (atomic) number, different neutron numbers and thus different mass numbers.

4Bromine has two isotopes: 50.7% bromine-79 and 49.3% bromine-81. What is the approximate relative atomic mass of bromine?

A.79.0

B.80.0

C.79.99

D.81.0

Explanation: Ar ≈ (0.507 × 79) + (0.493 × 81) = 40.053 + 39.933 = 79.986 ≈ 79.99. Relative atomic mass is the abundance-weighted average of isotopic masses.

5What is the electronic configuration of a phosphorus atom (atomic number 15) using s, p notation?

A.1s2 2s2 2p6 3s2 3p3

B.1s2 2s2 2p6 3s2 3p6

C.1s2 2s2 2p6 3s1 3p4

D.1s2 2s2 2p6 3s2 3d3

Explanation: Phosphorus has 15 electrons. Filling by the Aufbau principle: 1s2 2s2 2p6 3s2 3p3 (total 15).

6First ionisation energy is defined as the enthalpy change for which process?

A.X(g) → X+(g) + e−

B.X(s) → X+(g) + e−

C.X(g) + e− → X−(g)

D.X+(g) → X2+(g) + e−

Explanation: First ionisation energy is the enthalpy change when one mole of gaseous atoms forms one mole of gaseous unipositive ions by losing one electron each: X(g) → X+(g) + e−.

7Across Period 3 from Na to Ar, the general trend in first ionisation energy is:

A.a steady decrease

B.a general increase with small irregularities

C.no overall change

D.a decrease only for the noble gases

Explanation: Nuclear charge increases across the period with similar shielding, so electrons are held more tightly and first IE generally rises. Irregularities occur at Mg→Al and P→S.

8Why is the first ionisation energy of aluminium lower than that of magnesium?

A.Al has a smaller nuclear charge than Mg

B.The 3p electron in Al is higher in energy and more easily removed than a 3s electron in Mg

C.Al has more shielding electrons than Mg

D.Mg has a larger atomic radius than Al, so Al always has higher IE

Explanation: Mg is 3s2; Al is 3s2 3p1. The 3p electron is higher in energy and less tightly held than a 3s electron, so Al has a lower first IE despite higher nuclear charge.

9In the Periodic Table, calcium is classified as which type of element?

A.s-block metal

B.p-block non-metal

C.d-block transition metal

D.f-block lanthanide

Explanation: Calcium ends in 4s2 and is in Group 2; it is an s-block alkaline earth metal.

10Relative molecular mass of CO2 (Ar: C = 12.0, O = 16.0) is:

A.28.0

B.32.0

C.44.0

D.56.0

Explanation: Relative molecular mass is the sum of the relative atomic masses of every atom in the formula. CO2 contains one carbon and two oxygens, so Mr = 12.0 + 2 × 16.0 = 44.0.

About the MATSEC IM Chemistry Exam

Malta Intermediate Matriculation (IM) Chemistry — IM 06 (2026) is administered by the MATSEC Examinations Board (University of Malta). Intermediate Matriculation subjects form part of the Matriculation Certificate pathway (two Advanced Level subjects, three Intermediate Level subjects and Systems of Knowledge, with group restrictions and a minimum of 44 grade points). Assessment for IM 06 follows the official 2026 syllabus scheme: one written paper of 3 hours in three sections (Section A eight to ten compulsory short-answer questions, 30 marks; Section B four to six compulsory structured questions, 30 marks; Section C two long questions from four, 40 marks), with the Periodic Table and a data sheet provided. This practice bank is an English-language MCQ study adaptation of syllabus knowledge and judgment, not an official paper simulation or substitute for required oral, practical, performance or project work.

Assessment

One written paper of 3 hours in three sections: Section A eight to ten compulsory fill-in short-answer questions (30 marks); Section B four to six compulsory structured questions (30 marks); Section C two long questions chosen from four (40 marks). The Periodic Table and a data sheet are provided. Practical laboratory work is recommended during the course but is not separately examined.

Time Limit

One written paper: 3 hours

Passing Score

Subject results are graded A, B, C, D, E (pass, A highest) or F (fail). For the Matriculation Certificate, Intermediate Level grade points are: A=10, B=8, C=6, D=4, E=2. The Certificate requires among other criteria a minimum total of 44 grade points from the required subject combination within five years (Matriculation Examination Regulations 2025).

Exam Fee

The MATSEC Examination Fees schedule applicable from the 2026 sessions publishes no base registration fee per subject; only additional charges are listed — late registration EUR 35 per subject, very late registration EUR 70 per subject, Revision of Paper at Intermediate Matriculation (IM) level EUR 40, and change in school EUR 35. Examination fees are not refundable. (MATSEC Examinations Board, University of Malta)

MATSEC IM Chemistry Study Tips from Top Performers

1Work from the official IM 06 2026 syllabus learning outcomes and scheme of assessment on um.edu.mt/matsec — examiners mark to those criteria.

2Practise timed written-paper style answers and any required oral, practical, performance or project work; MCQs alone cannot replace those components.

3Note Matriculation Certificate combination rules (groups, prohibited pairings, Systems of Knowledge, 44-point minimum) in the Matriculation Examination Regulations 2025.

4Use MATSEC past papers and marking schemes for personal study only; commercial reproduction requires MATSEC permission.

5Register within published First Session and September Second Session windows; late and very late fees apply per the 2026 fee schedule.
