GACE Chemistry (6-12) (712) is Georgia's chemistry content certification test, delivered by Pearson as a computer-based assessment built from four testlets totaling 100 selected-response questions. The testlets and their question counts are Atomic Structures and Properties (214) with 20 questions, Multi-Atomic Structures and Properties (215) with 30 questions, Chemical Reactions (216) with 30 questions, and Energy Changes (217) with 20 questions. To pass you must earn a cumulative score of at least 220 and also meet each testlet's minimum floor. The full assessment fee is $169 ($42.50 per testlet) and the total testing time for all four testlets in one appointment is 3 hours and 30 minutes. This free 100-question bank mirrors the official testlet weighting so candidates can practice across every content area.

1An atom of carbon-14 contains 6 protons. How many neutrons does this isotope contain?
A.8
B.6
C.14
D.20
Explanation: The mass number (14) equals the sum of protons and neutrons. Subtracting the 6 protons from the mass number of 14 gives 14 - 6 = 8 neutrons.
2Which subatomic particle has a negative charge and the smallest mass?
A.Electron
B.Proton
C.Neutron
D.Positron
Explanation: The electron carries a charge of -1 and has a mass of about 1/1836 that of a proton, making it the lightest of the three common subatomic particles. Its small mass is why atomic mass is dominated by protons and neutrons in the nucleus.
3A fictional element has three isotopes: mass 40.9 amu at 10.0% abundance, mass 43.9 amu at 30.0% abundance, and mass 45.9 amu at 60.0% abundance. What is the average atomic mass of this element?
A.44.8 amu
B.43.6 amu
C.42.1 amu
D.45.9 amu
Explanation: Average atomic mass is the weighted average of isotope masses: (40.9)(0.100) + (43.9)(0.300) + (45.9)(0.600) = 4.09 + 13.17 + 27.54 = 44.8 amu. The most abundant isotope (45.9 amu) pulls the average toward the higher value.
4Which of the following is the correct ground-state electron configuration for a neutral oxygen atom (Z = 8)?
A.1s2 2s2 2p4
B.1s2 2s2 2p6
C.1s2 2s2 2p2
D.1s2 2s4 2p2
Explanation: Oxygen has 8 electrons. Filling orbitals in order of increasing energy gives 1s2 (2 electrons), 2s2 (2 electrons), and 2p4 (4 electrons), totaling 8. The 2p subshell holds up to 6 electrons but only 4 are needed here.
5According to Hund's rule, how should electrons fill a set of three degenerate 2p orbitals when three electrons are added?
A.One electron in each of the three orbitals with parallel spins
B.Two electrons paired in one orbital and one electron in a second orbital
C.All three electrons paired into the lowest-energy orbital
D.One electron in one orbital and two paired in another
Explanation: Hund's rule states that electrons occupy degenerate (equal-energy) orbitals singly with parallel spins before any orbital is doubly occupied. This minimizes electron-electron repulsion, so three p electrons each go into a separate 2p orbital.
6Rutherford's gold foil experiment, in which a small fraction of alpha particles were deflected at large angles, provided evidence for which conclusion about atomic structure?
A.The atom has a small, dense, positively charged nucleus
B.Electrons travel in fixed circular orbits
C.Atoms are indivisible solid spheres
D.Mass is spread uniformly throughout the atom
Explanation: Most alpha particles passed straight through the foil, but a few were deflected sharply, showing that an atom's positive charge and most of its mass are concentrated in a tiny central nucleus. This refuted the earlier plum-pudding model of diffuse positive charge.
7When an electron in a hydrogen atom drops from a higher energy level to a lower energy level, what is observed?
A.A photon of light is emitted with energy equal to the difference between the levels
B.A photon is absorbed by the atom
C.The atom loses a proton
D.The electron gains kinetic energy from the nucleus
Explanation: When an electron falls to a lower energy level, the atom releases the energy difference as a photon. The photon's energy equals the energy gap, and its frequency follows E = hf, producing characteristic emission spectral lines.
8Which type of electromagnetic radiation has the highest energy per photon?
A.Gamma rays
B.Microwaves
C.Visible light
D.Radio waves
Explanation: Photon energy is directly proportional to frequency (E = hf) and inversely proportional to wavelength. Gamma rays have the highest frequency and shortest wavelength of the listed types, so they carry the most energy per photon.
9An atom emits an alpha particle during radioactive decay. How do its atomic number and mass number change?
A.Atomic number decreases by 2 and mass number decreases by 4
B.Atomic number increases by 1 and mass number is unchanged
C.Atomic number decreases by 1 and mass number decreases by 1
D.Atomic number is unchanged and mass number decreases by 4
Explanation: An alpha particle is a helium-4 nucleus containing 2 protons and 2 neutrons. Emitting it removes 2 from the atomic number and 4 from the mass number, transforming the atom into a different element.
10A radioactive isotope has a half-life of 8 days. If a sample initially contains 80 grams, how much remains after 24 days?
A.10 grams
B.20 grams
C.40 grams
D.5 grams
Explanation: Each half-life reduces the amount by half. In 24 days there are 24/8 = 3 half-lives: 80 to 40 (one), 40 to 20 (two), 20 to 10 grams (three). After 3 half-lives, 10 grams remain.
