The number of neutrons in any element depends on the isotope of the element you are referring to. Potassium has 24 isotopes, ranging from 32K to 55K. The most stable natural isotope is 39K, which would have 20 neutrons.
An alpha particle, consisting of two protons and two neutrons.
Radioactive decay is the process in which one isotope is changed into another isotope.
a cosmogenic isotope is an isotope that is created in space by cosmic rays
an isotope of an element
The atomic nucleus of potassium has 19 protons and a number of neutrons specific for each isotope (from 13 n to 36 n).
Potassium's atomic number is 19. That means that it must have 19 protons and 19 electrons to be electrically neutral. 39K is potassium's most common isotope, with 39 - 19 = 20 neutrons.
99.988% of potassium found in nature is not radioactive. 0.012% of natural potassium is 40K, which is radioactive and has a half life of about 1,248,000,000 years. Like all other elements, synthetic radioactive isotopes of potassium exist.

Any number with 'K' on the end means thousand. So 39K would be 39,000. Another examle - 100K would be 100,000.
$750 a week or $39K per year.
The cost of the iPhone 3GS 16GB will be 32K and 39K for 32GB.
