Question

Which of the following regarding a radioactive decay is/are true?

• A. All radioactive decay processes follow first order kinetics
• B. Radioactive nuclei acquire stability by interconversion of neutrons and protons
• C. Gamma rays gets deflected in the presence of magnetic field
• D. The reaction ${}_{92}^{235}U{+}_0^{1}n{\to }_{56}^{141}Ba{+}_{36}^{92}Kr+3_0^{1}n$ is an example of nuclear fission

Answer 1

Answer: (A), (B), (D)

The correct options are
A All radioactive decay processes follow first order kinetics
B Radioactive nuclei acquire stability by interconversion of neutrons and protons
D The reaction ${}_{92}^{235}U{+}_0^{1}n{\to }_{56}^{141}Ba{+}_{36}^{92}Kr+3_0^{1}n$ is an example of nuclear fission

a) All radioactive decay processes follow first order kinetics.
b) Radioactive nuclei acquire stability by interconversion of neutrons and protons to maintain a suitable n/p ratio.
c) Gamma rays do not get deflected in the presence of magnetic field because they are uncharged.
d) Nuclear fission is splitting of heavy nucleus into lighter nucleus. So, the given reaction is an example of nuclear fission.
