Detailed Solution
Download Solution PDFअवधारणा:
द्रव्यमान संख्या (A)= \(Z+N\)
द्रव्यमान संख्या (A)=प्रोटॉन की संख्या + न्यूट्रॉन की संख्या
\(Z\) = प्रोटॉन की संख्या
\(N\) = न्यूट्रॉन की संख्या
\(m_p\) = प्रोटॉन का द्रव्यमान
\(m_n\) = न्यूट्रॉन का द्रव्यमान
परमाणु द्रव्यमान = \(Zm_p+Nm_n\)
अतः सही उत्तर \(Zm_p+Nm_n\) है।
