Har cheez - aap, hawa, paani, sitare - atoms se bani hai. Ye itne chhote hain ki ek sui ki nok par crores aa jaayein! Aao is chhoti si duniya ke andar jhaankein.
6 detailed lessons, 3D Bohr Atom model, Build-an-Atom, Rutherford Gold-Foil simulation, aur Electron Shell-Filling - sab easy Roman Hindi mein.
Atom kya hai, electron/proton/neutron ki khoj, aur unke charge, mass aur position - detail mein.
Thomson, Rutherford (gold foil experiment) aur Bohr ke models - har ek ki khoj aur kamiyan.
Atomic number (Z), mass number (A), pehle 18 elements ke symbols aur unke atoms kaise bante hain.
Ek element (tatva) chuno aur uska atom 3D mein dekho - nucleus aur shells mein ghoomte electrons!
Bohr-Bury rules, 2n² formula, K/L/M/N shells, energy levels aur valence shell.
Protons, neutrons aur electrons add-remove karke element, charge aur mass live badalte dekho!
Valence electrons se valency (combining capacity) nikalna, aur elements react kyun karte hain.
Alpha particles ko gold foil par firo aur dekho zyada-tar seedhe nikal jaate, kuch mud jaate hain!
Ek hi element ke alag roop (isotopes), isobars, aur isotopes ke amazing uses - plus Bharat ka yogdaan.
Pehle 20 elements mein se koi chuno aur electrons ko K, L, M shells mein bharte dekho (2n² rule).
