Question of The Day12-02-2025

Who has been credited with the discovery of Proton?/ प्रोटॉन की खोज का श्रेय किसे दिया गया है?

Answer

Correct Answer : a ) E. Goldstein/ ई. गोल्डस्टीन

Explanation :

Electrons are negatively charged, protons are positively charged and neutrons have no charges.

Credit for the discovery of electron and proton goes to J.J. Thomson and E.Goldstein, respectively.

Rutherford’s alpha-particle scattering experiment led to the discovery of the atomic nucleus.

J. Chadwick discovered presence of neutrons in the nucleus of an atom.

Hence, option (a) is correct.

इलेक्ट्रॉन ऋणात्मक रूप से आवेशित होते हैं, प्रोटॉन धनात्मक रूप से आवेशित होते हैं और न्यूट्रॉन में कोई आवेश नहीं होता।

इलेक्ट्रॉन और प्रोटॉन की खोज का श्रेय क्रमशः जे.जे. थॉमसन और ई. गोल्डस्टीन को जाता है।

रदरफोर्ड के अल्फा-कण प्रकीर्णन प्रयोग से परमाणु नाभिक की खोज हुई।

जेम्स चैडविक ने परमाणु के नाभिक में न्यूट्रॉन की उपस्थिति की खोज की।

अतः, विकल्प (a) सही है।

Note: Proton was observed as H+ by Eugen Goldstein (1886). Identified in other nuclei (and named) by Ernest Rutherford (1917–1920).
