QUESTION 1
Based on the image attached, the equation shows the nuclear fission process. Calculate the total neutrons that will be produced in this reaction.
Lungile, a radio-pharmacist based at iThemba LABS, measures the activity of a specific isotope with a Geiger counter and it shows 200 counts per minute at 12h00. At 15h00, Lungile notices a huge decrease in activity and the the Geiger counter now only records 25 counts per minute. NOW Use the counts/minute to determine the half-life of this radioactive isotope? FULLY EXPLAIN your choice under the RATIONALE section below!
A. 3 hours
B. 8 hours
C. 1 hour
D. 2 hours
For this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha, Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. Suppose that a certain radioIsotope could emit TWO alpha particles, and its product (daughter nucleus) could then emit ONE beta-minus particle. The atomic number of the resulting element would be changed by
A. zero
B. minus 1
C. minus 2
D. minus 3
