Card 1Discovery of subatomic particles

What did the discovery of subatomic particles show about the atom?

Answer

The atom is not indivisible. It contains electrons, protons, and neutrons. This led to newer atomic models that explain atomic structure better than Dalton's model.

Card 2उपपरमाण्विक कणों की खोज

उपपरमाण्विक कणों की खोज ने परमाणु के बारे में क्या दिखाया?

Answer

परमाणु अविभाज्य नहीं है। इसमें इलेक्ट्रॉन, प्रोटॉन और न्यूट्रॉन होते हैं। इससे नए परमाणु मॉडल विकसित हुए जो डाल्टन के मॉडल की तुलना में परमाणु संरचना को बेहतर ढंग से समझाते हैं।…

Card 3मूलभूत कण

इलेक्ट्रॉन का आवेश और द्रव्यमान क्या है?

Answer

इलेक्ट्रॉन का आवेश = -1.602176 × 10^-19 C. इलेक्ट्रॉन का द्रव्यमान = 9.1094 × 10^-31 kg. यह ऋणावेशित मूलभूत उपपरमाण्विक कण है।…

Card 4Fundamental particles

What is the charge and mass of an electron?

Answer

Electron charge = -1.602176 × 10^-19 C. Electron mass = 9.1094 × 10^-31 kg. It is a negatively charged fundamental subatomic particle.

Card 5Fundamental particles

What is the charge and mass of a proton?

Answer

Proton charge = +1.602176 × 10^-19 C. Proton mass = 1.6726216 × 10^-27 kg. Proton was characterised in 1919 and is a positively charged particle.

Card 6मूलभूत कण

प्रोटॉन का आवेश और द्रव्यमान क्या है?

Answer

प्रोटॉन का आवेश = +1.602176 × 10^-19 C. प्रोटॉन का द्रव्यमान = 1.6726216 × 10^-27 kg. प्रोटॉन का चरित्रांकन 1919 में किया गया था और यह धनावेशित कण है।…

Card 7मूलभूत कण

न्यूट्रॉन क्या है और इसकी खोज किसने की?

Answer

न्यूट्रॉन एक विद्युत रूप से उदासीन मूलभूत कण है जिसकी खोज चैडविक ने 1932 में की थी। इसका द्रव्यमान प्रोटॉन की तुलना में थोड़ा अधिक होता है।…

Card 8Fundamental particles

What is the neutron and who discovered it?

Answer

The neutron is an electrically neutral fundamental particle discovered by Chadwick in 1932. Its mass is slightly greater than that of a proton.
