- Barium-133 is a radioactive element used in certain medical procedures. A sample of pure Barium133 has a mass of 18.000 grams. Determine the activity of the sample 47 years after it was created, in units of Curies.1 Radioactive decay Consider a chain of radioactive decays 1-2-3, where nuclei of type 3 are stable. We assume that we begin with No atoms of the parents at t= 0 and no atoms of the decay products are originally present. The decays constants are represented by A₁, A2. a) Compute N₁ (t) b) Compute N₂(1) c) Compute N₁ (1) d) Compute N₁ (t) + N₂(t) + Na(t) and interpret. e) Plot N₁ (t), N₂(t), and N₁(e) approximately and interpret them at small t and tooDoes the number of radioactive nuclei in a sample decrease to exactly half its original value in one half-life? Explain in terms of the statistical nature of radioactive decay.
- I need the answer as soon as possibleThe binding energy for a nucleus containing Z protons and N neutrons is defined as c²[ZM + Nm, - M] where M is the mass of the neutral atom containing the nucleus, the quantity in the parentheses is the mass defect, and c? = 931.5 MeV/u.The binding energy of a nuclide can also be written as E, = Am x 931.5 MeV/u where Am is the mass defect. The Figure below show the mass for neutral atom and the nucleons of a helium atom. SHe Binding energy Mass = 4.0026 u Mass = 4.0330 u Calculate the mass defect Am of a helium atom
