⚡ Where Did the Electron Go from Na? 🧪

Sodium (Na) has 11 electrons and loses 1 electron to become a stable Na⁺ ion. 🔥
But where does that electron go? 🤔
👉 It is transferred to another atom, forming an ionic bond!

Na → Na⁺ + e⁻ ⚛️

⚛️ Isobars — Same Mass Number, Different Atomic Numbers!

Isobars are atoms of different elements having the same mass number (A) but different atomic numbers (Z).

📌 Example: ¹⁴₆C and ¹⁴₇N
➡️ Same mass number = 14
➡️ Different atomic numbers = 6 and 7

💡 Remember: Isobars → Same A, Different Z.

⚛️ Sodium (Na): Atomic Structure Made Simple!

Atomic Number = 11 🔢
Mass Number = 23 ⚡
Therefore:
Protons = 11 | Electrons = 11 | Neutrons = 12

A perfect example of how atomic numbers and mass numbers reveal the structure of an atom! 🧪✨

🧪 ISOTOPES IN CHEMISTRY ⚛️

Atoms of the same element having the same atomic number but different mass numbers are called isotopes.

🔹 Same number of protons
🔹 Different number of neutrons
🔹 Similar chemical properties
🔹 Different physical properties

✨ Example: Hydrogen → Protium, Deuterium & Tritium

Learn the concept. Master the chemistry! 🚀📚

🧪 How is Na₂O Formed? | Class X Chemistry
Why is the formula of sodium oxide Na₂O? 🤔
Sodium loses 1 electron to form Na⁺, while oxygen gains 2 electrons to form O²⁻. Therefore, two sodium atoms combine with one oxygen atom to form Na₂O.
⚡ 2Na + O → Na₂O
📚 Understand the electron transfer → Understand the formula!

⚛️ Why Do Atoms Gain or Lose Electrons?
Atoms gain or lose electrons to achieve a more stable electronic configuration, usually by attaining a noble gas configuration.
🔹 Metals generally lose electrons → form positive ions (cations).
🔹 Non-metals generally gain electrons → form negative ions (anions).
✨ Stability is the key! Understanding electron transfer helps us understand how ionic bonds and compounds are formed.

Electrons are arranged in shells (energy levels) around the nucleus—starting from the closest shell (K) and moving outward (L, M, N…). Each shell has a fixed capacity (2n² rule), and electrons fill lower energy levels first for maximum stability ⚛️✨
