The half-life of a certain radioactive isotope is 3.24 years. If
a sample consisting of 6.023x1023 atoms were allowed to
decay, what percentage of the original number of atoms have decayed
after 2.0 years?
A) 50
B) 46
C) 32
D) 54
E) 60
A sample contains 80% of radioactive Carbon 13C.
Calculate the age of the sample if you knew that the half time of
Carbon isotope is 5730 year. Radioactive decay follows first-order
reaction kinetics.
how
do you calculate the sample mean and the standard deviation, when
you are only given significance level, sample size, hypotheaia teat
mean and sample mean(x-bar)?
Which type of nuclear decay is the following radioactive isotope likely to undergo?
All known stable isotopes are shown on the graph. The points form what is know as the "belt of stability".
If a radioactive isotope is above the belt of stability, think about what type of decay would decrease its N/Z ratio. If an unstable isotope is below the belt of stability, think about what type of decay would increase its N/Z ratio. If a radioactive isotope is...
