⚛️ Atomic Structure of Iron
Iron has twenty-six protons, thirty neutrons (in its most common isotope, Iron-56), and twenty-six electrons, with eight in its outer shell.
- 🟢 Protons: 26
- 🔴 Neutrons: 30 (Most common isotope, Iron-56)
- 🟡 Electrons: 26
💡 Did you know? Iron-57 and Iron-58 are stable isotopes used in medical and nuclear research!
🔬 Iron Properties
Iron is strong, malleable, and magnetic (ferromagnetic). It rusts in moist air but has a high melting point (1538°C / 2800°F).
🧬 How Was Iron Discovered?
Iron has been known since antiquity, with evidence of its use dating back to 3000 BCE in Mesopotamia and Egypt, extracted from ores like hematite.
