I tried writing jokes about the periodic table…Matthew Cohen/rd.com, shutterstock
The periodic table’s full name, of course, is the Periodic Table of the Elements. Need a refresher on your chemistry? This periodic table shows how we use every element in our lives.
Did you hear the one about cobalt, radon, and yttrium?Matthew Cohen/rd.com, shutterstock
Another chemical symbol-based chemistry joke: cobalt (Co), radon (Rn), and yttrium (Y—yes, it’s a real element).
Want to hear a joke about sodium, bromine, and oxygen?Matthew Cohen/rd.com, shutterstock
Sure enough, the chemical symbols of sodium (Na), bromine (Br), and oxygen (O) combine to form a casual way to tell someone you’re not interested in hearing a joke.
Did you hear about oxygen’s date with potassium?Matthew Cohen/rd.com, shutterstock
Potassium’s chemical symbol is K, which comes from the Latin word “kalium,” the English equivalent of which (“potash”) provides the root for “potassium.” (Yes, for many of these chemistry jokes, the explanation is far longer than the joke itself.) Here are some more short jokes anyone can easily remember.
If H2O is water and H2O2 is hydrogen peroxide, what is H2O4?Matthew Cohen/rd.com
Get it? What’s it 4?
Why do chemists find working with ammonia easy?Matthew Cohen/rd.com

What’s Iron Man’s favorite amusement park ride?Matthew Cohen/rd.com, shutterstock
The word “ferrous” describes a metal comprised mainly of iron, since “ferrum” is Latin for iron.
What’s the difference between chemistry jokes and physics jokes?Matthew Cohen/rd.com
This one riffs off of the alternate meanings of a major concept from each science: the periodic table and potential energy.
Why did the attacking army use acid?Matthew Cohen/rd.com
Acidic and basic chemicals on the pH scale can cancel each other out. Check out some more of our favorite funny jokes about the military.
What did the thermometer say to the measuring cylinder?Matthew Cohen/rd.com
Graduated cylinders are often used in science labs to measure chemicals. In this context, “graduated” means “marked with divisions or units of measurement.” And, of course, the word “degrees” has multiple meanings too.
What is Cole’s Law?Matthew Cohen/rd.com
There’s no real scientific law called Cole’s Law. This one mixes chemistry jokes with good ol’ food puns. Check out some more delightfully corny food puns here.
Why did the bear dissolve in water?Matthew Cohen/rd.com
Molecules that are “polar” have nothing to do with the Arctic. Instead, they have an unequal distribution of electrons. Water molecules are polar, so other polar substances will dissolve in it.
I dare you to lower your body temperature to absolute zero.Matthew Cohen/rd.com
Absolute zero, the coldest temperature theoretically possible, is equal to minus 273.15 degrees Celsius and zero degrees Kelvin (written out as 0K). These are the crazy, often funny things that happen when scientists experiment on themselves.
