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, ...

Prototypes based on iodine. The Vector Atomic work, which the team describe in Nature, represents a step towards overturning these limitations. Led by Vector Atomic co-founder and study co-author ...

Optical atomic clocks lose/gain a second over 300 billion years; a new iodine clock loses/gains a second every 9.1 million years, trading some accuracy for mobility June 20, 2025 e-Paper LOGIN Account ...

Fighting around Ukraine's Zaporizhzhia nuclear power plant is increasing concern about a dangerous atomic leak. Iodine prevents radiation absorption.

Here’s the background. After 1949, the US moved most of its atomic bomb testing ... The map below shows the deposits of Iodine-131 from a typical series of tests done in 1953: ...

For most patients, the old-fashioned basal metabolism test is a mild form of torture, but that would be no reason for discarding it if it were a consistently accurate test. The fact is that it is ...

1803: English chemist-physicist John Dalton starts using symbols to represent the atoms of different elements. Dalton, considered the father of modern atomic theory, made a logbook entry that day ...

Alas, Mendeleev's table was based on atomic mass rather than atomic number, so details like the placement of tellurium and iodine didn't work out. He thought it was a question of inaccurate ...
