Introduction: Atom Kya Hota Hai?

Duniya ki har ek cheez—chahe woh paani ho, hawa ho, ya fir aapka phone—chhote-chhote particles se bani hai jise hum Atom (Parmanu) kehte hain. Atom kisi bhi element ka sabse chhota building block hota hai, jo chemical reactions mein participate karta hai.

Structure of an Atom (Atom ki Sanrachna)

Ek atom ke andar main 3 subatomic particles paaye jaate hain:

• Proton: Ye positive charge (+) particle hota hai jo nucleus ke andar hota hai.
• Neutron: Ye neutral particle hota hai (ispar koi charge nahi hota) aur ye bhi nucleus ke andar hota hai.
• Electron: Ye negative charge (-) particle hota hai jo nucleus ke chaaron taraf fix orbits mein chakkar kaatata hai.

Important Atomic Models

Scientists ne atom ke structure ko samjhane ke liye alag-alag models diye:

1. Thomson's Model (Watermelon Model): Iske mutabiq atom ek positive sphere hai jisme electrons waise hi धंसे (embedded) hain jaise tarbooz mein beej hote hain.
2. Rutherford's Model: Iske anusar atom ka zyadatar hissa khali hota hai aur beech mein ek dense positive nucleus hota hai.
3. Bohr's Model: Is model ne bataya ki electrons nucleus ke chaaron taraf fixed energy levels (orbits) mein ghoomte hain.
