MATSEC Advanced Matriculation Chemistry (AM 06) is a University of Malta MATSEC subject assessed under the 2026 syllabus (Two written papers of 3 hours + practical Paper III of 3 hours). Results use grades A–E (pass) or F; AM 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.

1Which statement correctly describes the fundamental particles in a neutral atom of ^{23}Na?

A.11 protons, 12 neutrons and 11 electrons

B.11 protons, 11 neutrons and 12 electrons

C.12 protons, 11 neutrons and 11 electrons

D.23 protons, 11 neutrons and 12 electrons

Explanation: Sodium has proton number 11, so a neutral atom has 11 protons and 11 electrons. Mass (nucleon) number 23 means neutrons = 23 − 11 = 12.

2Chlorine has two main isotopes: ^{35}Cl (relative abundance 75.8%) and ^{37}Cl (24.2%). What is the relative atomic mass of chlorine to three significant figures?

A.35.0

B.35.5

C.36.0

D.37.0

Explanation: Ar = (0.758 × 35) + (0.242 × 37) = 26.53 + 8.954 = 35.484 ≈ 35.5 (three significant figures).

3A sample of a radioactive isotope has a mass of 80.0 g. After three half-lives, what mass of the original isotope remains?

A.40.0 g

B.20.0 g

C.10.0 g

D.5.0 g

Explanation: Each half-life halves the amount of the parent isotope: 80 → 40 → 20 → 10 g after three half-lives. (MATSEC AM limits half-life amount calculations to three half-lives.)

4Which nuclear equation correctly represents bombardment of ^{14}N by an α-particle producing ^{17}O?

A.^{14}N + ^{4}He → ^{17}O + ^{1}H

B.^{14}N + ^{4}He → ^{17}O + ^{1}n

C.^{14}N + ^{1}n → ^{17}O + ^{4}He

D.^{14}N + ^{4}He → ^{18}O + γ

Explanation: Rutherford’s historic reaction: nitrogen captures an α-particle (^{4}He) and emits a proton (^{1}H), giving ^{17}O. Mass numbers: 14 + 4 = 17 + 1; charges: 7 + 2 = 8 + 1.

5What is the ground-state electronic configuration of a chromium atom (Z = 24)?

A.[Ar] 4s^{2} 3d^{4}

B.[Ar] 4s^{1} 3d^{5}

C.[Ar] 3d^{6}

D.[Ar] 4s^{2} 3d^{5}

Explanation: Chromium is an exception to the simple Aufbau filling order: a half-filled 3d^{5} set with 4s^{1} is more stable than 4s^{2} 3d^{4}.

6Across Period 3 from Na to Ar, the first ionisation energy generally increases. Why is the first ionisation energy of Al lower than that of Mg?

A.Al has a larger nuclear charge than Mg

B.The outer electron in Al is in a 3p orbital, which is higher in energy and more shielded than the filled 3s^{2} of Mg

C.Al atoms are larger than Mg atoms so electrons are always harder to remove

D.Al has a higher first electron affinity than Mg

Explanation: Mg is 3s^{2}; Al is 3s^{2} 3p^{1}. Removing a 3p electron from Al is easier than removing a 3s electron from the filled, more stable 3s^{2} subshell of Mg, causing a dip in IE₁.

7Which hybridisation of carbon and molecular geometry pair is correct?

A.ethene (C=C): sp³, tetrahedral about each C of the double bond

B.ethyne (C≡C): sp, linear about each C of the triple bond

C.methane: sp², trigonal planar

D.benzene ring carbon: sp³, tetrahedral

Explanation: Each carbon in ethyne is bonded to two groups with a triple bond, requiring sp hybridisation and a linear arrangement (≈180°).

8Oxygen-18 labelling of ethanoic acid in esterification with ethanol shows the ^{18}O appears in the water produced, not in the ester. What does this indicate?

A.The C–OH bond of the alcohol is broken

B.The C–OH bond of the carboxylic acid is broken

C.Both C–O bonds break equally

D.No covalent bonds break; only hydrogen bonds rearrange

Explanation: If the labelled oxygen of RCOOH ends up in H₂O, the acyl–oxygen bond of the acid is cleaved and the alcohol oxygen becomes part of the ester. This is classic mechanistic tracer evidence in the syllabus.

9Electronegativity is best defined as

A.the energy released when an atom gains an electron in the gas phase

B.the ability of an atom in a covalent bond to attract the bonding electrons

C.the energy needed to remove the outermost electron from a gaseous atom

D.the number of electrons in the outer shell of an atom

Explanation: Pauling electronegativity measures how strongly an atom attracts shared electrons in a covalent bond. (Electron affinity and ionisation energy are different quantities.)

10Which species contains a dative (coordinate) covalent bond as typically exemplified at AM level?

A.H₂

B.NH₄⁺

C.NaCl

D.I₂

Explanation: In NH₄⁺, the fourth N–H bond forms when the lone pair on ammonia is donated to H⁺, giving a dative covalent bond (though once formed all N–H bonds are equivalent).

About the MATSEC AM Chemistry Exam

Malta Advanced Matriculation (AM) Chemistry — AM 06 (2026) is administered by the MATSEC Examinations Board (University of Malta). Advanced 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; AM grade points A=30, B=24, C=18, D=12, E=6). Assessment for AM 06 follows the official 2026 syllabus scheme: Paper I written 3 hours (40%): 6–10 compulsory structured questions answered on the paper. Paper II written 3 hours (40%): two sections of four extended-response questions each; answer five questions total (two from each section plus any one other). Paper III practical 3 hours (20%): open-book practical. Calculators permitted; specified constants provided on papers when applicable. 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, coursework or project work.

MATSEC AM Chemistry Study Tips from Top Performers

1Work from the official AM 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 such as Computing with Information Technology, 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. Revision of Paper at AM level is EUR 45.
