Free Year 7 Chemistry Quiz — 10 Questions, Instant Results

Free practice quizzes › Year 7 Science quiz › Chemistry

What Year 7 students need to know about chemistry

A short orientation first. Year 7 chemistry covers mixtures and solutions, separation techniques such as filtration and evaporation and the properties of materials.

Our tutors wrote and checked these questions against the Victorian Curriculum, which is why the wording and the difficulty match what a Year 7 student meets at school.

The usual chemistry errors at Year 7

If your child gets a question wrong here, it is worth checking whether one of these is behind it. They are the chemistry misconceptions RHZ tutors correct most often with Year 7 students:

• Atoms and molecules are used interchangeably.
• Mass is thought to be lost in a chemical reaction.
• Equations are balanced by changing subscripts.

Each of these is fixable in a session or two once it has been named, which is why the results panel below shows the correct answer and an explanation rather than just a score.

How to practise chemistry at home

Practice works when it is short, regular and specific. For chemistry, our tutors suggest:

1. Draw particle diagrams for solids, liquids and gases.
2. Learn the first twenty elements.
3. Balance equations daily for a week.

For Years 7 to 10, practise the two things tests reward: knowing the terms and applying a concept to a new situation. Past questions are the best resource.

How this chemistry quiz works

Every set on this page is a seeded selection of 10 from the 25 chemistry questions that pass our quality gate. A different seed gives a different set, and there are many more combinations than any one student will need. The correct answers never appear in the page source; the browser asks our server for them after you press Mark my answers.

Because every question here is on chemistry, a low score is a clear signal and a high score is genuinely reassuring for this topic. What it cannot tell you is whether the other Year 7 science topics are equally secure, or how far above the year level the student can go; the free Skills Check covers both.

Question 1

Chemistry

Which particle has a negative charge?

Neutron Proton Electron Nucleus

Question 2

Chemistry

Rusting of iron is an example of a…

Chemical change Dissolving Physical change State change

Question 3

Chemistry

Which of these is a mixture?

Carbon Oxygen gas Pure water Salt water

Question 4

Chemistry

A student mixes iron filings and sulfur powder together, then heats the mixture strongly. The product no longer responds to a magnet and cannot be separated back into iron and sulfur by physical means. Which conclusion is BEST supported by these observations?

A chemical reaction occurred only because heat was applied — without heat, mixing iron and sulfur would also form the same product. A physical change occurred because no new elements were created during the reaction. A physical change occurred because the iron and sulfur particles are still present inside the product. A chemical reaction occurred because the properties of the product are different from the starting materials and the change cannot be reversed by physical methods.

Question 5

Chemistry

Water's chemical formula is…

H₂O O₂ CO₂ H₂O₂

Question 6

Chemistry

A row in the periodic table is called a…

Group Period Family Shell

Question 7

Chemistry

A student adds heat to a liquid until it turns into a gas. What is this process called?

Melting Freezing Condensation Evaporation

Question 8

Chemistry

Which of these is a physical change rather than a chemical change?

Melting an ice cube Rusting a nail Baking a cake Burning a piece of paper

Question 9

Chemistry

A student burns magnesium ribbon in air. The white powder produced has a mass greater than the original magnesium ribbon. Which statement best explains this increase in mass?

Magnesium atoms gained mass when they were heated. The white powder contains extra hydrogen atoms absorbed from the air. Heat energy from burning was converted into mass inside the magnesium. Oxygen from the air chemically combined with the magnesium to form magnesium oxide.

Question 10

Chemistry

The centre of an atom is the…

Nucleus Electron shell Molecule Proton cloud

How to read a score out of 10

9 or 10 out of 10

The easy and at-level content is secure. The useful question now is how far above the year level the student can go, which a ten-item quiz cannot show. The free Skills Check adds stretch and challenge questions on every topic so you can see the ceiling as well as the floor.

7 or 8 out of 10

Solid, with one or two specific gaps. Look at which topic the incorrect answers came from (the results panel names the weakest topic) and spend a week on that topic before re-testing with a different seed.

5 or 6 out of 10

Some core ideas are shaky. The pattern matters more than the score: two misses in the same topic is a gap; misses scattered across topics usually means reading the question too fast. Either way, the Skills Check will tell you which.

4 or fewer out of 10

Foundations from an earlier year are probably missing, which is common and fixable. Try the quiz one year level down to confirm, then talk to a tutor about a short catch-up plan rather than more of the same practice.
