Who Discovered Proton? Rutherford Explained in Hindi-English

🔍 Introduction – Proton: Ek Basic Par Powerful Particle

Aaj ki modern science ka agar foundation dekhen, toh subatomic particles – electron, proton aur neutron – uska main base hain. Inmein se proton ek positively charged particle hai jo atom ke nucleus mein hota hai. Par kya aap jaante hain ki proton ki khoj kisne ki thi? Aur kaise science ne is discovery ko accept kiya?

Is article mein hum jaanenge:

• Proton ki khoj kisne ki aur kaise?

• Kaun scientist iske peeche the?

• Proton ka charge, mass aur properties

• Proton therapy aur modern uses

• Common questions jo students Google par search karte hain

Chaliye shuru karte hain!

🧑‍🔬 Proton Ki Khoj Kisne Ki? – Who Discovered Proton?

Proton ki khoj British scientist Ernest Rutherford ne 1917 mein ki thi.
Unhone yeh discovery ek experiment ke through kiya jisme unhone nitrogen gas par alpha particles ka bombardment kiya tha.

🧬 Rutherford ka Gold Foil Experiment:

Rutherford pehle hi 1911 mein nucleus ka concept propose kar chuke the. Par 1917 mein unhone ek aur experiment kiya jahan unhone dekha ki hydrogen ions (yaani protons) emit ho rahe hain jab alpha particles ko nitrogen atom se takraya gaya.

Isi observation se unhone conclude kiya:

“Hydrogen nucleus is a fundamental building block of all atomic nuclei.”
Aur isi hydrogen nucleus ko unhone naam diya “Proton”.

🆚 Confusion: Goldstein Ya Rutherford – Proton Ki Khoj Mein Kaun Sahi?

Ye sawal kai baar students ko confuse karta hai. Kai log kehte hain Goldstein ne proton discover kiya, toh kai Rutherford ko credit dete hain.

💡 Clarification:

• Goldstein (1886) ne Canal Ray Experiment kiya jisme unhone positive rays dekhe the.
  Par unhone specific particle (proton) identify nahi kiya.

• Rutherford (1917) ne experimentally hydrogen nucleus ko identify kiya aur scientifically prove kiya.
  Unhone uska naam “Proton” diya.

👉 Final Credit goes to Rutherford for actual discovery and naming.

⚛️ Proton Kya Hota Hai? – What is a Proton?

Proton Ki Basic Properties:

Property	Value
Charge	+1 (Positive)
Mass	1.672 × 10⁻²⁷ kg
Symbol	p⁺
Location in Atom	Nucleus ke andar
Discovered By	Ernest Rutherford (1917)

Proton ka Role:

• Atomic Number define karta hai (e.g. Hydrogen ka 1 proton = Atomic No. 1)

• Atom ke mass ka major part banata hai (with neutrons)

• Chemical identity fix karta hai (e.g. 6 protons = Carbon)
