The half-life of a radioactive substance is the time taken for:
A
All of it to decay
B
One-fourth of it to decay
C
Half of it to decay
D
None of it to decay
Correct Answer: Option C — Half of it to decay
Explanation:
Half-life is defined as the time required for exactly half of the radioactive nuclei in a given sample to undergo decay, and it is a charact...
Half-life is defined as the time required for exactly half of the radioactive nuclei in a given sample to undergo decay, and it is a characteristic constant for each radioactive isotope.
