About this deck
Use this periodic table flashcard deck to review all 118 chemical elements by name, symbol, and atomic number. It is designed for chemistry class, science quizzes, and quick general knowledge practice.
The cards run from hydrogen to oganesson, so the deck works as a complete reference set rather than a short sample. Each card also includes a short study note with its period, broad family, or a practical memory hook.

What you will learn
- The name of every chemical element in the modern periodic table.
- The official chemical symbol for each element.
- Atomic numbers from 1 through 118.
- Useful context such as element family, period, common uses, or where the element appears.
How to study this deck
- Start with name to symbol recall, then reverse the prompt mentally from symbol to element name.
- Break the complete deck into small packs if you are new to chemistry: first 20, first 36, then the full table.
- Use quiz mode after one pass through the cards to catch symbols that look similar.
Recommended study setup
- Start with about 18 cards per session; the full deck is roughly 7 first-pass packs.
- Write, calculate, point to, or sketch the answer before flipping whenever the topic allows it.
- Use quiz mode after one recall pass; study notes appear only after you answer.
Scope
This complete deck focuses on element names, symbols, atomic numbers, and short study notes. It does not try to teach atomic mass, electron configuration, oxidation states, or full periodic trends.
