About This Quiz

Chemistry in college might have meant a few things to you. Maybe it was the class you took, or maybe it was something you shared with someone else. This quiz is all about the elements, compounds and equations that make up the science of chemistry. Fasten your seatbelts and get ready to go back in time to college!

Do you know the names of the elements on the periodic table? What about their atomic numbers? Do you know all about the noble gases and antimatter? If that's too easy, then tell us what an isotope is! Crack open a dictionary and study up on your chemistry terms, you'll need to know them to ace this quiz!

Have you ever heard of the Mpemba effect? Then tell us all about it! Maybe you're more familiar with the Bohr model and what it is used for? Or are you more knowledgeable on chemical reactions and how they work? Grab those beakers and start experimenting with this quiz!

Calling all chemists – get ready to prove all of that knowledge you gained back in college and make your chemistry teacher proud.  Put your science skills to good use by taking this quiz – and don't cause a chemical reaction!

Elementary particles do not have what?
a home
a purpose
a name
particles within themselves
Elementary particles are not made up of other particles. Elementary particles can also make up larger particles making larger objects. When you think of an elementary particle, think of fermions, which are one type of the particles!

What can affect the size of an atom?
the compound
whether it is day or night
the temperature
The temperature can affect the size of an atom. The hotter it is, the larger and farther away the components of an atom get from one another. In colder conditions, they're closer together and thus the atom is smaller in size.
the proton size

What type of nucleons do not have a charge?
protons
nucleus
ions
neutrons
Neutrons do not have any charge, unlike protons, which are positively charged. Did you know that neutrons are made up of two down quarks and one up quark?

What determines the atomic number of an element?
the amount of protons in the nucleus
Each element on the periodic table of elements has an atomic number. Its number is determined by the amount of protons in the nucleus. For example, hydrogen's atomic number is 1, meaning that there is only one proton in the nucleus.
its place on the chart
the order it was discovered
the time it takes to reach a boiling point

What is an isotope?
different elements, same number of protons
same element, same number of protons
same element, different number of neutrons
An isotope is the same element but one has less or more neutrons than the other. Isotopes can be any of the elements as there are no exceptions. This can also affect the mass of the elements, as they will not be equal.
different elements, same number of neutrons

How many atoms are needed to make a molecule at the least?
one
two
In order to make a molecule, there need to be at least two atoms that are fused together. The way they become fused together is through a chemical bond, that can include as many atoms as possible.
14
83

What is the process of losing and gaining electrons called?
loss
subtraction
elimination
redox
This process is called redox, which is a mix of reduction and oxidization, the names used for each of the processes. These processes also affect the oxidization number because of the number of electrons being moved around.

Which of the following is not a type of chemical bond?
ionic bonds
Van der Waals force bonds

The sequence H20 is called what?
an atomic number
Newtons Law
an equation
a molecular formula
H20 is a molecular formula that means one part hydrogen, two parts oxygen. The formula also refers to the amount of atoms in the elements.

Is it true or false that helium is lighter than oxygen?
True
This is true. For example, this is why balloons are filled with helium, and it's also what makes them float! But did you know that the higher you go, the thinner the oxygen gets?
False

What is the law of constant composition?
It has a fluid and a solid compound.
It has a constant atomic value.
It has the same elements and same mass.
The law of constant composition calls for equal elements and equal mass. It is a rule for all elements that generally is followed. It's common for the elements to be measured in a ratio format to better understand the parts in the compound.
It is made up of four or more elements.

Rest mass and volume makes up what?
air
atoms
particles
matter
Rest mass and volume work together to make up matter, which is also made of particles. Did you know that matter can come in all different forms? Solid, liquid and even gas can all be classified as matter.

Which of the following is not a noble gas?
neon
xenon
oganesson
oxygen
Oxygen is not one of the noble gases, as there are only six of them. The other three are radon, krypton and argon which fit the bill. Oganesson is a very rare element, in fact only a few atoms of it have ever been detected!

What branch of chemistry focuses on living things?
theoretical chemistry
synthetic chemistry
biochemistry
Biochemistry is all about chemicals within the bodies of living things. The chemicals that are studied in this area are things like protein and carbohydrates and how they work within the body.
mathematical chemistry

Is it true or false that chlorine expands when it freezes?
True
False
This is false. The element that does this is actually water. As it turns into ice, the molecules expand, making the ice take up more volume.

What happens during a chemical reaction?
There is always an explosion.
Solid turns to gas.
The bonds break.
During a chemical reaction, the bonds of the atoms break as the entire composition transforms. The reaction can change the entire form of the substance.
