Why build your own atomic structure quiz

Atomic structure appears in nearly every intro chemistry course, but each instructor stresses different details, so a generic chemistry quiz on atomic structure can miss what your exam covers. DeckOwl builds one from your own material, so the questions follow your lecture slides and textbook chapter.

Multiple choice, true/false and short answer questions on atomic number, mass number and isotopes
Explanations for every answer, so wrong choices become study notes
Free plan: 3 generations per month, studying in the browser, no credit card needed
Plus exports to PDF and DOCX; Pro adds QTI 2.1 and Moodle XML

Example atomic structure chemistry quiz questions

What subatomic particle determines which element an atom is?The proton. The number of protons, called the atomic number, defines the element.

True or false: isotopes of the same element have different numbers of protons.False. Isotopes differ in neutron number, not proton number, so they share the same atomic number.

What is the maximum number of electrons in the second shell (n = 2)?8. The formula 2n^2 gives 2 x 2^2 = 8.

Why is almost all of an atom's mass concentrated in its nucleus?Protons and neutrons are each about 1,836 times as massive as an electron, so the nucleus holds nearly all the mass.

What is the electron configuration of a neutral oxygen atom?1s2 2s2 2p4. Oxygen has 8 electrons, which fill 1s and 2s completely and leave 4 in the 2p subshell.

Questions from your own material

Upload PDFs, DOCX, PPTX, plain notes or photos of a textbook page. Every quiz is built from the text you provide.

Multiple choice, true/false and short answer

Mix question types in one quiz. Every answer includes an explanation, so a wrong choice becomes a study note.

Export when you need it

Plus exports to PDF and DOCX. Pro adds QTI 2.1 and Moodle XML for course platforms.

How it works

Upload your notes

Add a PDF, slide deck, DOCX file or a photo of your chemistry notes.

Choose the question types

Pick multiple choice, true/false or short answer, and how many questions you want.

Study and review

Answer in the browser, read the explanations, then retake the questions you missed.

Because the quiz comes from your upload, it can cover protons, neutrons, electrons, isotopes and electron configuration in the order your class taught them. Each explanation shows why an answer about electron shells or mass number is correct, which is where most of the learning happens.

Frequently asked questions

How many questions should an atomic structure quiz include?

Eight to fifteen questions usually cover the core ideas of protons, neutrons, electrons, isotopes and electron shells without overloading one session. If your material is dense, start with a shorter quiz and add questions on the topics you miss.

What should I review before taking an atomic structure quiz?

Focus on the difference between atomic number and mass number, how isotopes differ from one another, and how electrons fill shells. Working a few examples on paper before the quiz makes the explanations easier to follow.

Can I export the quiz to Moodle or QTI?

Yes, but that requires the Pro plan, which includes QTI 2.1 and Moodle XML export. PDF and DOCX export are included in Plus.

Is there a free way to try it?

The Free plan includes 3 generations per month and studying in the browser, and you do not need a credit card to start. Exports require a paid plan.
