The radioisotope that has the longest half-life is the best to use in powering planet and space exploration vehicles because the
y can travel farther. Which radioisotope is the best to use?
2 answers:
Answer:
Uranium-238 is the radioisotope which is best to use.
Explanation:
Half-life : The time in which the concentration of a reactant is reduced to half of its original value is called half life period.
As it has been given that radioisotope that has the longest half-life is best to use as power source planet and space exploration vehicles:
Uranium 238 is with the highest value of half life which is equal to years.
Answer:
U-238
Explanation:
For a given radioisotope, half life can be defined as the time taken for the isotope to decay into one-half of its original amount. Mathematically, this is expressed as:
where k = rate constant for the radioactive decay process
Greater the t1/2 longer will be its stability.
Based on the given data, U-238 has the largest half life and therefore will be best suited for applications mentioned.
