⚛️ Atomic Structure of Chlorine
Chlorine has seventeen protons, eighteen neutrons (in its most common isotope, Chlorine-35), and seventeen electrons, with seven in its outer shell.
- 🟢 Protons: 17
- 🔴 Neutrons: 18 (Most common isotope, Chlorine-35)
- 🟡 Electrons: 17
💡 Did you know? Chlorine-37, another stable isotope, makes up about 24% of natural chlorine and is used in scientific studies!
🔬 Chlorine Properties
Chlorine is highly reactive, forming compounds with most elements. It's toxic and has a strong, pungent odor, detectable even at low concentrations.
🧪 How Was Chlorine Discovered?
In 1774, Swedish chemist Carl Wilhelm Scheele produced Chlorine by reacting manganese dioxide with hydrochloric acid, though he didn't recognize it as an element.
