WebPotassium naturally occurs in 3 isotopes: 39 K (93.2581%), 40 K (0.0117%), 41 K (6.7302%). 39 K and 41 K are stable. The 40 K isotope is radioactive; it decays with a half-life of 1.248 × 10 9 years to 40 Ca and 40 Ar. Conversion to stable 40 Ca occurs via electron emission in 89.3% of decay events. Conversion to stable 40 Ar WebThe remaining 0.0117% is 40 K — an unstable isotope with a half life of 1.26 × 10 9 years (1.26 billion years). Potassium 40 has three decay modes: beta decay, positron emission, and electron capture. When 40 K undergoes beta decay it transmutes into 40 Ca — the most abundant isotope of calcium.
