Card 1परमाणु द्रव्यमान इकाई

परमाणु द्रव्यमान इकाई और उसका मान किलोग्राम में बताइए।

Answer

परमाणु द्रव्यमान इकाई को 1 12C परमाणु के द्रव्यमान के 1/12 के रूप में परिभाषित किया जाता है. सूत्र: 1u = एक 12C परमाणु का द्रव्यमान / 12 = 1.992647×10^-26 kg / 12 = 1.660539×10^-27 kg. अर्थ: u परमाण्व…

Card 2Atomic mass unit

State the atomic mass unit and its value in kilograms.

Answer

Atomic mass unit is defined as 1/12 of the mass of one 12C atom. Formula: 1u = mass of one 12C atom / 12 = 1.992647×10^-26 kg / 12 = 1.660539×10^-27 kg. Meaning: u is the unit used for atomic and nucl…

Card 3Atomic mass unit

Why are atomic mass units used instead of kilograms for nuclei?

Answer

Nuclear masses are extremely small in kilograms, so kilograms are not convenient. A carbon atom has mass 1.992647×10^-26 kg, while a proton has mass 1.67262×10^-27 kg. Using u makes comparisons and ca…

Card 4परमाणु द्रव्यमान इकाई

नाभिकों के लिए किलोग्राम के बजाय परमाणु द्रव्यमान इकाइयों का उपयोग क्यों किया जाता है?

Answer

नाभिकीय द्रव्यमान किलोग्राम में अत्यंत छोटे होते हैं, इसलिए किलोग्राम सुविधाजनक नहीं है. एक कार्बन परमाणु का द्रव्यमान 1.992647×10^-26 kg है, जबकि एक प्रोटॉन का द्रव्यमान 1.67262×10^-27 kg है. u का उप…

Card 5समस्थानिक

समस्थानिक क्या होता है?

Answer

समस्थानिक किसी एक ही तत्व के वे नाभिक होते हैं जिनका परमाणु क्रमांक Z समान होता है, लेकिन द्रव्यमान संख्या A भिन्न होती है क्योंकि उनके न्यूट्रॉनों की संख्या अलग होती है. उदाहरण: ड्यूटेरियम 2_1H और ट्…

Card 6Isotopes

What is an isotope?

Answer

Isotopes are nuclides of the same element having the same atomic number Z but different mass number A because they have different numbers of neutrons. Example: deuterium 2_1H and tritium 3_1H are isot…

Card 7Isotopes

A chlorine atom has isotopes of masses 34.98 u and 36.98 u with abundances 75.4% and 24.6%. Find its average atomic mass.

Answer

Given: m1 = 34.98 u, m2 = 36.98 u Abundances: 75.4% and 24.6% Formula: average mass = (75.4×34.98 + 24.6×36.98)/100 Step 1: 75.4×34.98 = 2637.492 Step 2: 24.6×36.98 = 909.708 Step 3: sum = 3547.200 St…

Card 8समस्थानिक

एक क्लोरीन परमाणु के समस्थानिकों के द्रव्यमान 34.98 u और 36.98 u हैं तथा प्रचुरताएँ 75.4% और 24.6% हैं। उसका औसत परमाणु द्रव्यमान ज्ञात कीजिए।

Answer

दिया गया: m1 = 34.98 u, m2 = 36.98 u प्रचुरताएँ: 75.4% और 24.6% सूत्र: औसत द्रव्यमान = (75.4×34.98 + 24.6×36.98)/100 चरण 1: 75.4×34.98 = 2637.492 चरण 2: 24.6×36.98 = 909.708 चरण 3: योग = 3547.200 चरण …
