WebPotassium-39, potassium-40 and potassium- 41 are three isotopes of potassium. They are different in their masses or mass number. Potassium- 39 has an atomic mass of 39 amu or mass number is 39, Potassium- 40 has an atomic mass of 40 amuor mass number is 40, and Potassium- 41 has an atomic mass of 41 amuor mass number is 41. WebStable potassium isotopes are one of the emerging non-traditional isotope systems enabled in recent years by the advance of Multi-Collector Inductively-Coupled-Plasma Mass-Spectrometry (MC-ICP-MS). In this review, we first summarize the geochemical and cosmochemical properties of K, its major reservoirs, and the analytical methods of K …

It consist of molecules so when it passed into the ionization chamber, the electrons are knocked off, and give molecular ion, Cl 2+. The ions are not stable so some will form chlorine atom and a Cl + ion. This process is called fragmentation. Cl 2+ → Cl + Cl + how fast does usain bolt run in km
