Ionization Energy | First & Second Ionization Energy / Why E₂ is greater then E₁/ chemistry9/ part 1

In this lecture, we will understand Ionization Energy in a very easy and conceptual way. This topic is important for Class 9 Chemistry and helps you understand the formation of positive ions. 🔥 Topics Covered: ✅ What is Ionization Energy? ✅ First Ionization Energy (IE₁) ✅ Second Ionization Energy (IE₂) ✅ Why is IE₂ is greater than IE₁? ✅ Example of Sodium (Na) ✅ Why removing the second electron requires more energy ✅ Easy concept for understanding ionization energy ⚛️ First Ionization Energy The energy required to remove the first electron from one mole of isolated gaseous atoms to form one mole of gaseous positive ions. Na(g) → Na⁺(g) + e⁻ ⚛️ Second Ionization Energy The energy required to remove the second electron from one mole of gaseous +1 ions to form one mole of gaseous +2 ions. Na⁺(g) → Na²⁺(g) + e⁻ 💡 Important: Second ionization energy is always greater than first ionization energy because after the first electron is removed, the remaining electron experiences a stronger attraction from the nucleus. 📖 Useful for students preparing for: Punjab Boards, Federal Board (FBISE), KPK Boards, Sindh Boards, Balochistan Boards, AJK Board, CBSE, ICSE, and other Pakistan & India boards.
