What doesTax code K39 mean?
Tax code K39 indicates that an employee has a "K" tax code for the current tax year, which typically means that they have a tax adjustment that results in a higher tax rate due to having unpaid tax from previous years or receiving benefits that exceed their personal allowance.

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.
