About This Quiz

When we think about chemistry, we tend to think about the periodic table. Everyone knows helium, hydrogen, copper and gold. However, have you kept up with the newest elements? In 2016, nihonium, Moscovium, Tennessine, and oganession were officially named and added to the periodic table. Don't worry! We won't ask you to name all 118 known elements. Considering, some elements have had more than one name throughout history, that would be a hard feat for even the most acclaimed chemist to accomplish.

Besides, chemistry is so much more than naming elements and finding them on the periodic table. If anything, memorizing the periodic table is boring. The exciting part of chemistry is how those elements interact and seeing the chemical reactions. Explosions, solvents and the states of matter are what gets kids excited.

This quiz will test you on chemistry knowledge that you learned in school. Remember the various states of matter? How about the groups on the periodic table? Do you know the different types of bonds? Can you explain what the pH scale measures? What about the difference between an exothermic and an endothermic reaction? Find out how well you remember those chemistry lessons! We may ask about condensation, but we won't be condescending!

Which common liquid has the chemical formula H20?

Adult woman and adult men have different percentages of water in their bodies. Men are made up of approximately 60 percent of water, while women contain about 55 percent water.

2 of 35
NaCl is the chemical formula for what?

Salt has many uses. It lowers the melting point of snow or ice. It is also can remove calcium and magnesium compounds from water.

3 of 35
What is the atomic number of an element equivalent to?

In an uncharged atom, the atomic number is also equal to the number of electrons in the atom. Neutrons have no impact on the atomic number. However, they do impact atomic mass.

4 of 35
What kind of charge does a proton have?

Protons have 1,836 times the mass of an electron. They are found in all atomic nuclei.

5 of 35
Which part of an atom has no charge?

In the periodic table, the number of protons and neutrons comprise the mass number. To get the number of neutrons, you subtract the number of protons from the mass number.

6 of 35
Which element has an atomic number of 1?

Deuterium is a rare from of hydrogen. It was discovered by Harold Urey in 1931. It has one proton and one neutron in its nucleus.

The word isotope comes from Greek. It is a combination of isos, which means "equal," and topos, which means "place."

8 of 35
What is helium's atomic number?
5
2

Helium was first detected in the sun's corona. The element takes its name from the Greek word, "helios," which means sun.

9 of 35
Ag is the chemical symbol for which precious metal?

Silver is considered a precious metal. It also has the most electrical conductivity, which makes it useful in electrical circuits.

10 of 35
Which element is not radioactive?

An atom is radioactive when an unstable nucleus loses energy, resulting in the release of radiation. Elements with an atomic number 84 or higher are radioactive.

11 of 35
Which common cleaning product has the chemical formula NH3?

Ammonia is used as a fertilizer and in the manufacture of synthetic fabrics. It is also used as a household cleaner.

12 of 35
Which is not a state of matter?

There are four basic states of matter: solid, liquid, gas and plasma. Plasma is a gas that is positively charged as opposed to a regular gas which has an equal number of protons and neutrons.

13 of 35
Carbon dioxide has how many oxygen atoms?
2
1
6

In a solid state, carbon dioxide is called dry ice. Carbon dioxide must be put under pressure at low temperatures in order to become dry ice.

14 of 35
What are the members of the periodic table's group 18 better known as?

There are seven noble gases. In order from top to bottom, they are helium, neon, argon, krypton, xenon, radon and oganesson.

15 of 35
When an atom loses an electron, what does it become?

Ions have different names depending on their charge. A positively charged ion is called a cation. A negatively charged ion is called an anion.

Electrolytes are substances that ionize in a solution. Examples of electrolytes include potassium, calcium, sodium and magnesium.

17 of 35
When two or more atoms bond, what forms?

Compounds are the smallest particle of a compound that retains the chemical properties of a compound. The atoms in a molecule may be held together by covalent bonds.

18 of 35
Solutions with a pH greater than 7 are called what?

Litmus tests are used to determine whether a substance is a acidic or basic. A red result means the substance is an acid. A blue result means the substance is base.

19 of 35
Which of the following is not a type of chemical bond?

A chemical bond is the attraction between two atoms, ions or molecules. They enable the formation of chemical compounds.

20 of 35
What is the smallest unit of matter?

"Atom" comes from the Greek word for "uncuttable." While we now know that atoms are made of protons, electrons and neutrons, a Greek named Democritus believed that atoms could not be broken up smaller. The name stuck.

21 of 35
Which number of the pH scale is considered neutral?
1
7
4

The pH scale is a logarithmic scale that goes from 1 to 15. The human body is close to neutral. It has a pH of approximately 7.4.

22 of 35
Which type of molecule has an uneven sharing of electrons?

Polar bonds are partly ionic, whereas covalent bonds have an equal sharing of electrons. Polar bonds occur between two nonmetal atoms that have different numbers of electrons.

23 of 35
What kind of chemical reaction absorbs heat from the environment?

Exothermic reactions give off energy, which causes the surrounding area to feel warmer than before. Endothermic reactions cause the surrounding area to feel cold because it has absorbed the surrounding heat.

24 of 35
Which information is not given on the periodic table?

Chemical symbols do not always match up with the current scientific name. For example, sodium has the chemical symbol Na. Sodium, which is known as natrium in Latin, is one of many elements that kept the abbreviation for its Latin name.

25 of 35
What is the only metal that is liquid at room temperature?

Mercury sulfide is a bright-red paint pigment that was used in the Paleolithic area. It is also known as cinnabar. Due to mercury sulfide's toxicity, the pigment is rarely used today.

26 of 35
What kind of solvent is water known as?

Water holds the title "universal solvent" because it dissolves more substances than any other liquid. Water's ability to attach to both negative and positive compounds is why it is able to dissolve so many substances.

27 of 35
Which of the following is not an alkali metal?

One the periodic table, alkali metals make up the first group on the far left. In order from top to bottom, the alkali metals are lithium, sodium, potassium, rubidium, cesium and francium.

28 of 35
What does a catalyst do to a chemical reaction?

Many catalysts are enzymes, which naturally occur. There are also some solid catalysts, most of which are metals. Examples of catalysts are oxides and sulfides.

29 of 35
At what point does a liquid turn into a gas?

Boiling points are determined using the air pressure at sea level. However, adding solutes or changing the pressure will affect the boiling point.

30 of 35
Which element has a chemical symbol K?

Potassium makes up 2.4 percent of the Earth's crust by mass, making it the seventh most abundant metal there. Each year, mines extract about 35 million tons.

31 of 35
The periodic table is organized by what?

Russian scientist Dmitri Mendeleev created the periodic table. He noticed a pattern in certain groups, so, in his version, he left gaps for elements that were unknown in his time.

32 of 35
What element do all organic compounds contain?

An organic compound has carbon atoms covalent linked to other elements. However, there are some compounds that contain carbon, but are not classified as organic. Some examples are cyanides, carbonates, and carbides.

33 of 35
Liquids have a definite volume, but no definite what at room temperature?

Bromine and mercury are the only elements liquid at standard temperature and pressure. Four other elements become liquid slightly above room temperature. They are cesium, Francium, Gallium and rubidium.

34 of 35
What is the ratio of mass to volume of an object called?

Masses of objects are compared to a platinum-iridium cylinder with a mass of one kilogram. The cylinder is called the International Prototype Kilogram. It is kept in Sèvres, France at the International Bureau of Weights and Measures.
