Relation: e-λt = 3 e-λt = 1/3 eλt = 3 N₀ = 3N 2 / 10 Atomic number of an element is Z. What is the atomic number of daughter nucleus after β⁺ has emitted from the parent material: A+1 A–2 Z+1 Z−1 3 / 10 The symbol for neutrino is ν β γ η 4 / 10 Total mass of separated nucleons is always less than the same number of nucleons in a nucleos more than the same number of nucleons in a nucleos equal to the same number of nucleons in a nucleos massless 5 / 10 If mass number A remains same but atomic number Z changes, the decay causing the change is: α β γ all 6 / 10 1 curie ≈ 3.7 × 10⁴ Bq 3.7 × 10¹⁰ Bq 10⁶ Bq 10³ Bq 7 / 10 If Δm = 0.008 u, Binding Eenergy = 7.45 MeV 74.5 MeV 0.74 MeV 745 MeV 8 / 10 The phenomena of radioactivity is induced chemical dependent spontaneous impossible in nature 9 / 10 Nuclear force is long-range short-range infinite range repulsive 10 / 10 λ = ln2 / T1/2.
