Atomic Structure Quizzes & Trivia

Every type of matter is made up of atoms. How much do you know about atoms and their structure? Every atom has a nucleus but did you know that they also have a surrounding cloud of protons, neutrons, and electrons? Did you know that the atomic number of an atom is based on the number of protons?

The nucleus is surrounded by an “electron cloud” but did you know that it doesn’t have a distinct boundary? Most people know that protons have positive charges and electrons have a negative charge, but did you know that neutrons don’t carry a charge at all? Can you name the force that attracts electrons to protons? Do you know how many protons a copper atom has? Check out some of our quizzes and see how many questions like these you can answer!
