Mixed-difficulty questions from across the Chemistry syllabus. Tap "Show answer" after each to check yourself.

Q1 · Difficulty 1/3

A finite resource obtained from the Earth is:

  1. crude oil
  2. sunlight
  3. wind
  4. tidal energy
Show answer & explanation
✓ Answer: A — crude oil
Crude oil is finite (non-renewable).
Q2 · Difficulty 1/3

A covalent bond is formed when atoms:

  1. gain protons
  2. transfer electrons
  3. share a pair of electrons
  4. lose all their electrons
Show answer & explanation
✓ Answer: C — share a pair of electrons
A covalent bond is a shared pair of electrons between two non-metal atoms.
Q3 · Difficulty 1/3

Which sub-atomic particle has a relative mass of 1 and a relative charge of +1?

  1. Electron
  2. Proton
  3. Neutron
  4. Ion
Show answer & explanation
✓ Answer: B — Proton
Award 1 mark for identifying the proton as the particle with relative mass 1 and charge +1. A is incorrect — electrons have negligible mass (1/1840) and charge −1. C is incorrect — neutrons have relative mass 1 but no charge. D is incorrect — an ion is not a sub-atomic particle.
Q4 · Difficulty 1/3

The Group I metals are also known as the:

  1. noble gases
  2. transition metals
  3. alkali metals
  4. halogens
Show answer & explanation
✓ Answer: C — alkali metals
Group I elements (lithium, sodium, potassium…) are the alkali metals.
Q5 · Difficulty 1/3

The relative charge of a proton is:

  1. −1
  2. 0
  3. +2
  4. +1
Show answer & explanation
✓ Answer: D — +1
Protons carry a charge of +1.
Q6 · Difficulty 1/3

How many electrons are shared in a single covalent bond?

  1. One
  2. Two
  3. Three
  4. Four
Show answer & explanation
✓ Answer: B — Two
A single covalent bond consists of one shared pair — that is, two electrons.
Q7 · Difficulty 1/3

Most atoms bond in order to achieve:

  1. more protons
  2. fewer neutrons
  3. a positive charge
  4. a full (stable) outer electron shell
Show answer & explanation
✓ Answer: D — a full (stable) outer electron shell
Atoms bond to gain a full, stable outer shell of electrons, like that of the noble gases.
Q8 · Difficulty 1/3

What salt is formed when hydrochloric acid reacts with sodium hydroxide?

  1. Sodium chloride
  2. Sodium nitrate
  3. Sodium carbonate
  4. Sodium sulfate
Show answer & explanation
✓ Answer: A — Sodium chloride
HCl + NaOH → NaCl + H₂O. Hydrochloric acid always produces chloride salts. Sulfuric acid → sulfate salts. Nitric acid → nitrate salts.
