Iodine has fifty-three protons, seventy-four neutrons (in its only stable isotope, Iodine-127), and fifty-three electrons, with seven in its outer shell.
- 🟢 Protons: 53
- 🔴 Neutrons: 74 (Stable isotope, Iodine-127)
- 🟡 Electrons: 53
💡 Did you know? Iodine sublimates into a vivid purple gas without melting!
🔬 Iodine Properties
Iodine is shiny, reactive, and sublimates at 113°C (235°F). It's a solid at room temperature but turns into a violet vapor when heated.
🧬 How Was Iodine Discovered?
In 1811, French chemist Bernard Courtois found Iodine while extracting potassium from seaweed ash, noticing its purple vapor. It's named from Greek "iodes" (violet).
