Sample GTLE Subject Specialism Chemistry Practice Questions

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

1Which state of matter is characterized by having a definite volume but no definite shape?

A.Solid

B.Liquid

C.Gas

D.Plasma

Explanation: Liquids have a definite volume because their particles are close together, but they have no definite shape because the particles can slide past one another. Solids have both definite shape and volume, while gases have neither.

2What are atoms of the same element that have the same number of protons but different numbers of neutrons called?

A.Isomers

B.Isotopes

C.Allotropes

D.Isobars

Explanation: Isotopes are atoms of the same element with the same atomic number (protons) but different mass numbers due to a different number of neutrons. For example, carbon-12 and carbon-14 are isotopes of carbon.

3Which subatomic particle has a relative mass of approximately 1 amu and a positive charge of +1?

A.Electron

B.Neutron

C.Proton

D.Positron

Explanation: A proton is a subatomic particle found in the nucleus of an atom, possessing a mass of approximately 1 atomic mass unit (amu) and a positive charge of +1. Electrons are much lighter with a negative charge, and neutrons are neutral.

4What is the maximum number of electrons that can occupy a single atomic orbital according to the Pauli Exclusion Principle?

A.1

B.2

C.6

D.8

Explanation: The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers. This means a single orbital can hold a maximum of two electrons, and they must have opposite spins.

5Which of the following elements has the ground-state electron configuration of 1s2 2s2 2p6 3s2 3p6?

A.Neon

B.Argon

C.Krypton

D.Chlorine

Explanation: The sum of the exponents in the electron configuration (2+2+6+2+6) is 18, which corresponds to the atomic number of Argon (Ar). It has a stable octet valence shell (3s2 3p6).

6Which group of elements in the periodic table is known as the alkali metals?

A.Group 1

B.Group 2

C.Group 17

D.Group 18

Explanation: Group 1 elements (except Hydrogen) are known as the alkali metals. They have a single valence electron and are highly reactive metals.

7What is the general periodic trend for electronegativity across a period and down a group?

A.Increases across a period, increases down a group

B.Decreases across a period, increases down a group

C.Increases across a period, decreases down a group

D.Decreases across a period, decreases down a group

Explanation: Electronegativity increases from left to right across a period due to increasing nuclear charge and decreasing atomic size. It decreases down a group because of the increased shielding effect and atomic radius, which reduces the pull of the nucleus on bonding electrons.

8Which type of bond is formed by the sharing of one or more pairs of electrons between two non-metal atoms?

A.Ionic bond

B.Covalent bond

C.Metallic bond

D.Hydrogen bond

Explanation: A covalent bond is formed when two non-metal atoms share valence electrons to achieve stable octet configurations. Ionic bonds involve electron transfer, and metallic bonds involve a delocalized pool of electrons.

9Which of the following substances contains a triple covalent bond between its atoms?

A.Oxygen (O2)

B.Nitrogen (N2)

C.Chlorine (Cl2)

D.Hydrogen (H2)

Explanation: A nitrogen molecule (N2) has a triple covalent bond (one sigma and two pi bonds) because each nitrogen atom shares three electrons to complete its valence octet. Oxygen has a double bond, and chlorine and hydrogen have single bonds.

10What is the molecular geometry of a methane (CH4) molecule?

A.Linear

B.Trigonal planar

C.Tetrahedral

D.Octahedral

Explanation: Methane has a central carbon atom bonded to four hydrogen atoms with no lone pairs. According to VSEPR theory, these four bonding domains repel each other to occupy positions at the corners of a regular tetrahedron, with bond angles of 109.5°.

About the GTLE Subject Specialism Chemistry Exam

The Chemistry Subject Specialism paper is a 100-item multiple-choice exam administered by the National Teaching Council (NTC) for teacher candidates seeking to teach Chemistry in Senior High Schools (SHS) or Technical/Vocational institutes in Ghana. It covers core strands from the Ghanaian NaCCA secondary chemistry curriculum and introductory tertiary chemistry: Atomic Structure & Bonding, Stoichiometry, Physical Chemistry (Kinetics, Equilibrium, Energetics), Inorganic Chemistry, Organic Chemistry, and Chemistry Teaching Pedagogy. The exam assesses both theoretical subject knowledge (including mathematical calculations for stoichiometry, pH, and electrochemistry) and pedagogical content knowledge (lab safety, student misconceptions, and practical setups).

Assessment

Computer-based multiple-choice chemistry content test taken alongside the general professional knowledge paper and a pedagogy paper. It tests both secondary/introductory tertiary chemistry content knowledge and subject-specific pedagogical content knowledge.

Time Limit

2 hours (refer to specific instruction on exam paper; timetables allocate 2 hours for subject content papers)

Passing Score

50% (candidates must score at least 50 out of 100 marks to pass this paper)

Exam Fee

GH¢450 fresh (all 3 papers); re-sit GH¢150/210/385; indexing GH¢50 fresh (National Teaching Council (NTC) Ghana)
