Web3 dec. 2024 · It has two isotopes Cl-35 and Cl-37, so it contain 3 atoms of Cl-35 and 1 atom of Cl-37. 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 +
