AQA GCSE Chemistry 8462 Higher
Tier Paper 1 Practice Paper:
Independent Exam Preparation,
Questions and Revision
Description
This independent practice paper is designed to mirror the format
content and assessment objectives of the AQA GCSE Chemistry
Higher Tier Paper 1 examination. It covers all five Paper 1 topics
Atomic Structure and the Periodic Table Bonding Structure and the
Properties of Matter Quantitative Chemistry Chemical Changes and
Energy Changes. The paper includes required practical content on
making salts electrolysis temperature changes and neutralisation.
Questions reflect the AQA assessment model testing knowledge
application and analysis. This resource supports revision and exam
technique development.
Section 1 Questions 1 to 50
1. Which subatomic particle has a relative charge of plus one and a
relative mass of one?
A. Electron
B. Neutron
C. Proton
D. Nucleus
C. Proton
, Page |2
Protons have a relative charge of plus one and a relative mass of one.
Electrons have a relative charge of minus one and a relative mass of
one over eighteen thirty six. Neutrons have no charge and a relative
mass of one.
2. An atom of chlorine has an atomic number of seventeen and a mass
number of thirty five. How many neutrons does it contain?
A. Seventeen
B. Eighteen
C. Thirty five
D. Fifty two
B. Eighteen
Number of neutrons equals mass number minus atomic number.
Thirty five minus seventeen equals eighteen.
3. Which scientist proposed the nuclear model of the atom following
the alpha particle scattering experiment?
A. John Dalton
B. J J Thomson
C. Ernest Rutherford
D. Niels Bohr
C. Ernest Rutherford
Rutherford alpha particle scattering experiment led to the nuclear
model in which most of the atom is empty space with a small dense
positively charged nucleus.
4. Why did the plum pudding model have to be replaced?
, Page |3
A. It could not explain why atoms are neutral.
B. It could not explain why some alpha particles were deflected by
large angles.
C. It did not include electrons.
D. It was proposed by a scientist who was not qualified.
B. It could not explain why some alpha particles were deflected by
large angles.
The plum pudding model could not account for the large angle
deflection of some alpha particles observed by Rutherford which
indicated a concentrated positive charge in a tiny nucleus.
5. Which of the following is an isotope of carbon twelve?
A. An atom with six protons and seven neutrons
B. An atom with six protons and six neutrons
C. An atom with seven protons and six neutrons
D. An atom with twelve protons and twelve neutrons
B. An atom with six protons and six neutrons
Isotopes have the same number of protons but different numbers of
neutrons. Carbon twelve has six protons and six neutrons.
6. Why do isotopes of the same element have the same chemical
properties?
A. They have the same mass number.
B. They have the same number of electrons in their outer shell.
C. They have the same number of neutrons.
D. They have the same relative atomic mass.
B. They have the same number of electrons in their outer shell.
, Page |4
Chemical properties are determined by the number of electrons in the
outer shell. Isotopes have the same electron configuration.
7. In the periodic table elements are arranged in order of increasing
what?
A. Mass number
B. Atomic number
C. Relative atomic mass
D. Number of neutrons
B. Atomic number
The modern periodic table arranges elements by increasing atomic
number which is the number of protons.
8. Which group of the periodic table contains the noble gases?
A. Group one
B. Group two
C. Group seven
D. Group zero
D. Group zero
Group zero also called Group eighteen contains the noble gases
helium neon argon krypton xenon and radon.
9. Why are noble gases unreactive?
A. They have a full outer shell of electrons.
B. They have no electrons in their outer shell.
C. They are all gases at room temperature.
