A modified and more robust version of https://ankiweb.net/shared/info/1749433712. If you catch any mistakes in the cards, please do mention them in GitHub issue tracker. I'll look into them as I get time.
The cards that are from the Lanthanoids and Actinoids and use Period and Group to identify should be suspended. Incase your cards are not suspended, kindly suspend them yourself as these are unfortunately unanswerable as they don't have a unique answer.
Changelog 25/12/2024 - Uploaded the deck 27/12/2024 - Moved around some cards and suspended the Period and Group cards for Lanthanoids and Actinoids 28/04/2025 - Added a separate sub-deck for cards which are to be suspended
