All Quizzes
We are constantly surrounded by invisible reactions, from the food cooking in a kitchen to the battery powering your phone right now. Learning the fundamentals of matter gives you a clear prospective on how everything around us is built and transformed.
This quiz set guides you through the core concepts of matter, chemical bonds, the periodic table, and how different substances interact with one another. You will see how these rules apply to real-world situations, such as understanding how cleaning products work, why certain materials rust, or even how ingredients react when you are baking a cake. It transforms abstract science into practical, everyday knowledge.
Mastering chemistry requires dedicated practice, and these interactive quizzes provide a helpful way to test your memory and reinforce what you learn. They are designed to be completed in quick sessions that easily fit into a busy day. You can take each quiz as many times as you need to feel comfortable with the material.
Fun Fact: While we often think of water as a simple liquid, it actually expands when it freezes, which is incredibly rare for liquids. Most substances shrink and become denser when they turn solid, but water behaves differently, which is why ice cubes float in your glass and why aquatic life can survive under frozen lakes.
1. Alkali Metals
This chemistry quiz runs through 12 questions on the alkali metals, the reactive elements in Group 1 of the periodic table. You will handle a mix of fill-in-the-blank, multiple choice, and true-or-false, with prompts like "What is the element symbol of sodium?" and "Which alkali metal is the lightest?" Recommended for intermediate students brushing up on the periodic table. A neat fact from the questions explains a common puzzle: potassium's symbol is K because the element was originally called kalium. You will also see just how strongly these metals react with plain water.

2. Alkaline Earths
Here are 12 questions on the alkaline earth metals, the Group 2 elements that sit right next to the alkali metals. The quiz blends fill-in-the-blank, multiple choice, and true-or-false, asking things like "The atomic number of ___ is 20" and "What is the color of magnesium?" Recommended for intermediate students who already know their way around the periodic table. One fact that tends to stick: magnesium takes its name from Magnesia, an ancient region in Greece. You will also discover which of these metals Pierre Curie helped discover and how their reactivity compares with the alkali metals.

3. Carbon Dioxide
This 11-question quiz looks at carbon dioxide, the gas we breathe out and plants take in.
You will answer fill-in-the-blank and true or false items, with prompts such as What is the solid form of carbon dioxide? and Carbon dioxide is absorbed by trees and plants during ___.
One of the more surprising facts is that the solid form, known as dry ice, skips the liquid stage entirely and turns straight into a gas, a change called sublimation.
You will also touch on where the gas comes from and why it can be dangerous in large amounts.
Recommended level: intermediate.

4. Copper
This 12-question quiz covers copper, from its place on the periodic table to its everyday uses.
You will work through fill-in-the-blank and true or false items, with questions like What is the atomic number of copper? and The characteristic green film on copper is called ___.
A fact that tends to stick with people is that copper can be drawn out into wire thinner than a human hair, which is part of why it shows up in so much wiring.
You will also meet two common alloys it forms with other metals.
Recommended level: intermediate.

5. Element Symbols
This 12-question quiz tests how well you can match chemical symbols to their elements.
You are given a symbol like Mg or Ca and name the element it stands for, working through a steady run of common ones.
The non-obvious part is that several symbols do not line up with their English names at all, because they trace back to older Latin words, which is why a handful look nothing like the element you might expect.
Spotting which ones carry those Latin roots is really the key to the trickier items in this set.
Recommended level: intermediate.

6. Gold
This 12-question quiz digs into gold, its physical properties, and how its purity is measured.
You will answer fill-in-the-blank and true or false items, with prompts such as How many carats are there in pure gold? and What metal dissolves gold?
A striking fact is that gold is the most malleable metal there is, soft enough to be hammered into sheets so thin that they are known as gold leaf.
You will also learn about the acid test used to tell real gold apart from other metals, and what white gold actually is.
Recommended level: intermediate.

7. Halogens
This 12-question quiz introduces the halogens, the reactive group of nonmetals found in the periodic table.
You will work through fill-in-the-blank and true or false items, with questions like What is the heaviest halogen? and What halogen is used in bleaching and disinfectant?
A connection to everyday health turns up here too: a shortage of iodine, one of the halogens, is what leads to the swelling condition known as goiter.
You will also compare how reactive the different members of the group are, and learn what compounds they form together.
Recommended level: intermediate.

8. Hydrogen
This 12-question quiz covers the basics of hydrogen, the first element on the periodic table, and it works well if you are just getting started in chemistry.
You will answer a mix of fill-in-the-blank and true or false items, such as What is the atomic number of hydrogen? and Hydrogen produces ___ when burned.
One detail that catches a lot of students off guard is what the name actually means. Hydrogen translates to "water maker," which makes sense once you see that burning it produces water.
Recommended level: beginner.

9. Laboratory Apparatus
If you are learning your way around a science lab, this 12-question quiz helps you match common equipment to the job it does.
Questions ask things like What container is used for holding and measuring liquids? and What is used for measuring temperature?, with a few true or false statements mixed in to test your reading.
A small piece of safety advice in here surprises some people: regular sunglasses are not the same as proper lab eye protection, so they are not what you reach for during every activity.

10. Oxygen
Oxygen keeps us alive, and this 11-question quiz takes a closer look at what it actually is and how it behaves.
Expect fill-in-the-blank prompts like Oxygen is the by-product of ___. alongside true or false checks about its color, taste, and the elements it bonds with.
Here is something many learners do not expect: the word oxygen means "acid producer." Scientists once believed oxygen was part of every acid, which turned out to be wrong, but the name stuck anyway.
Recommended level: beginner.

11. Rare Gases
This quiz introduces the rare gases, also called the noble gases, across 12 questions.
You will work through items like Which gas is used to inflate balloons? and Kr is the element symbol of ___., plus a handful of true or false statements.
One fact worth holding onto is that these gases sit together in Group 18 of the periodic table and barely react with anything, which is why they earned the "noble" label. One of them, though, is actually radioactive.

12. Silver
Silver is more than just jewelry, and this 12-question quiz digs into its chemistry and everyday uses.
You will see questions such as What is the atomic number of silver? and What compound is used for small batteries?, with a few true or false items at the end.
A point that often surprises students is that pure silver is actually quite soft, so it gets mixed with other metals for strength. It also beats every other metal as a conductor of heat and electricity.
