Iodine has a similar atomic mass to xenon but is more abundant and much cheaper. It can also be stored as an unpressurised solid, meaning it has the potential to simplify satellite designs.

The classic example is of iodine (atomic mass 126.9) and tellurium (127.6). In terms of atomic mass, iodine should have come before tellurium, but Mendeleev chose to swap them, ...
