However, since the pattern of pre-solar potassium isotopes found in non-carbonaceous chondrites matched that seen on Earth, these meteorites are the probable source of our planet's potassium.

The results indicated that the potassium isotope with a neutron number of 32 does not conform with criteria of magic neutron number. The results were published in Nature Physics journal.

The team wanted to see the ratios of different "isotopes" of potassium and rubidium. An isotope is a variation of an element that has different numbers of neutrons in its atomic nucleus.

What potassium isotopes could say about Alzheimer’s risk. Using 20 blood samples — 10 from people with Alzheimer’s disease and 10 without — Mahan and his team compared levels of potassium ...

Researchers measured the potassium isotope compositions in 20 meteorites confirmed to have originated on Mars, selected as representative of the composition on Mars.

Since the lunar soil samples provided by NASA had previously had their lighter and heavier isotopes of potassium and rubidium quantified, Nie’s team used calculations to determine which ...

Potassium is the least volatile of the volatile elements, and thus the one likeliest to not have its isotopes altered by the heat and radiation of the early solar nebula.
