I want to learn the periodic table and for each element I want to learn three data points. f.e.:
O - Oxygen - 8
now I want to create a card deck which has always one information on the front side and two information on the back side. f.e.
- O / Oxygen-8
- Oxygen / O-8
- 8 / O-Oxygen
Does anyone have a an Idea how to create this without having to enter everything three times for each element?
