Is the element Potassium stable or radioactive?

Answer 1

99.996% of calcium found in nature is not radioactive. 0.004% of natural calcium is radioactive 46Ca, and there are also trace quantities of radioactive 41Ca found naturally. Like all other elements, calcium has synthetic radioactive isotopes.
The calcium you deal with in every day life is not, no. Some isotopes are, but they are not found in natural calcium deposits

Answer 2

The elements that have at least one isotope that is not radioactive and at least one radioactive isotope found in nature (other than as a result of human activity or in traces as a fission product in uranium ore) are as follows (ordered by period and atomic number):

1. hydrogen
2. beryllium, carbon
3. sodium, aluminum, silicon, chlorine, argon
4. potassium, calcium, vanadium, chromium, manganese, iron, nickel, germanium, selenium
5. rubidium, strontium, zirconium, molybdenum, palladium, cadmium, indium, tin, tellurium, iodine
6. cesium, lanthanum, cerium, neodymium, samarium, europium, gadolinium, dysprosium, lutetium, hafnium, hafnium, tantalum, tungsten, rhenium osmium, platinum, lead

For most of these, the radioactive isotope is found only in trace quantities.

All elements have synthetic radioactive isotopes.

Answer 3

In general, it is stable, although there are heavier isotopes that could be radioactive.

Answer 4

Stable, but don't drop it in water

Answer 5

calcium is stable. Look it up.

Answer 6

Stable.
