K-39 is the most abundant, constituting about 93 % of the atoms in naturally occurring potassium.
What is the value of the bradex number 84-K41-6.4?
The Bradex number 84-K41-6.4 refers to a specific collectible item, typically associated with the Bradford Exchange or similar collectible companies. This number helps identify a particular piece in their catalog, often indicating the year of issue, the series, and the specific item. To determine its value, one would need to consult recent sales data, collector's guides, or auction results specific to that item. Values can vary based on condition, rarity, and demand among collectors.
What are the seventeen isotopes in potassium?
I believe 24 isotopes have been identified with atomic mass ranging from 32 to 55. Only three occur naturally, K39 (93% of the total), K41 (7%) and the radioactive K40 (0.01%). The others have very short half-lives, as small as a few nano-seconds in some cases.
