Is there a reliable way to store all stable elements?

This is a follow-up to question about a transmuting 3D-printer

Assume you need to store all stable elements in a spaceship. On board, a chemical assembler is used to compose everything, if you have a blueprint and the right amount of needed elements.

Is there a common way to store the, maybe as salt or in a certain composition to make handling easier?

Density is critical here, you want to store as much of the elements as possible in a limited volume.

How would you keep them separate? Would you? Can there be a universal element mix, composed of all elements? I guess not, because some of the are rather reactive.

Is there a way to generate unstable elements on-demand, if you have a fusion reactor?

EDIT: Assume the main products are

• Food, Water, Personal Care, Medicine
• Technical components (simple) and Ammo. So mostly metal and future alloys.
• Electronics and magnetic components.

What would you need to hold in storage for such products?

Assume future tech, I'll accept plausible handwaves, but please keep them as minor as possible.
