Why generate your own nomenclature cards

Naming ionic and covalent compounds gets easier when each rule has its own card, and chemistry nomenclature flashcards work best when they follow your course's own examples. A generic printable set may cover prefixes you never studied, or skip the polyatomic ions your exam uses.

  • Formula-to-name and name-to-formula cards from the same source
  • Polyatomic ion endings such as -ate and -ite drilled as separate cards
  • Roman numeral charge cards for transition metals
  • Exports to Anki or CSV on Plus, so the deck can follow you across apps
Example chemistry nomenclature flashcards
Name NaClSodium chloride. Ionic compounds name the metal first, then the nonmetal with an -ide ending.
Name CO2Carbon dioxide. Covalent compounds use prefixes, and di- means two oxygen atoms.
Name Fe2O3Iron(III) oxide. The Roman numeral gives the iron charge, since oxygen is always -2 in oxides.
Name H2SO4Sulfuric acid. Acids ending in -ic come from polyatomic ions ending in -ate, such as sulfate.
Name the ion NO3-Nitrate. The -ate ending has more oxygens than the -ite ion, which is nitrite, NO2-.
Generate the full set

Starts from your material

Upload a PDF, slide deck, text notes or a photo of a board. The cards cover the compounds and rules your class actually uses.

Spaced repetition

Cards you miss come back sooner, and ones you know fade to longer gaps. Spaced repetition is included with Plus.

Export when you need it

Plus exports to PDF, DOCX, Anki and CSV, so you can print a review sheet or move cards into another app.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of your page. Text in photos is read with text recognition.

Generate your cards

DeckOwl writes question-and-answer flashcards from the material. Check them and remove anything you do not need.

Review on a schedule

Study in the browser on the free plan. Spaced repetition and exports are part of Plus.

Start with the chapter your instructor covered last. Upload the slides or lab handout, generate a set, and split it into formula-to-name cards and name-to-formula cards. Review the hard ones daily and let the easy ones space out.

Frequently asked questions

How many flashcards should I make for a nomenclature unit?

Most students do well with one card per rule and one card per common compound or ion, usually 40 to 80 cards for a unit. Start with the names your instructor used in class, then add the exceptions from the homework.

What should I memorize first when learning chemical names?

Learn the charges of common monoatomic and polyatomic ions first, since most naming rules depend on them. Then practice the ionic rules before moving to covalent prefixes and acid naming.

Can I export my chemistry flashcards?

Exports are part of the paid plans. Plus includes PDF, DOCX, Anki and CSV export, and the free plan lets you study in the browser.

Is there a free plan, and does it need a credit card?

The free plan includes 3 generations per month and browser study, and you do not need a credit card to start. Plus is $39 per year or $7.99 per month, and students get 40% off with a school email.
