The Mnemosyne Project

Contains two sets of cards:

(1) Elements and Elemental Symbols
(2) Atomic Number

The primary difference between this and DBOOKSTA's set is that, in addition to items like this:

Q: Symbol: Cu
A: Copper

it now asks the opposite of the question, like this:

Q: Copper
A: Symbol: Cu

Contains two Categories:

1. Elemental Symbols

2. Atomic Number, which covers elements up to atomic number 100 excluding Lanthanides and Actinides.
