Electron offer karo — meter neeche/green gaya toh atom ne liya (energy released), upar/red gaya toh mana (absorbed). Doosra electron? Hamesha repulsion.
🧭 How to use this lab
1“Offer electron” dabao — atom leta hai (energy release) ya mana karta hai.
2← → arrows se element badlo (Cl sabse bhookha; Be/Mg/N/noble gas mana karte).
32nd electron “force” karke repulsion khud feel karo.
About this lab
Offer an electron to a gaseous atom and watch the energy meter. Almost every atom is hungry — it gulps the electron and releases energy. Only Be, Mg, N and the noble gases refuse. And nobody wants the second electron.
