Lab 11: PhET LAB: Alpha DecayNames: __Section: _____J Group 4______________________________________Investigating Alpha Decay1. Start on theSINGLE ATOMtab.Observe the decay of Polonium-211.After each decay, press the RESET NUCLEUSbutton to watch the process again.Write below a description of alpha decay for Po-211.
Complete the following alpha decay equations, usingas a resource:2. Polonium-211:¿¿84211Po→82207Pb+4¿2He¿3. Radium-226:88226Ra→¿+24α222/86RN4. Uranium-238:¿¿¿90234Th+24α238/92U5. Plutonium-240:94240Pu→¿+24α240/92U6. Americium-241:4¿95241Am→93237Np+¿2He¿7. How is alpha decay used in everyday life? (give at least two uses)
Investigating Half-Life of Alpha Decay8. Click theMULTIPLE ATOMStab. Execute five trials to determine the number of parent and daughter nuclei at onehalf-life. Complete the table below.
