Regarding the Question of the Precise Time at Which a Radioactive

question 64

Multiple Choice

Regarding the question of the precise time at which a radioactive nucleus will decay:

• A) The time is completely unpredictable (i.e., we cannot know anything about it), because we cannot know anything about an object as small as an individual nucleus.
• B) The time is precisely predictable, provided we have sufficient information about the condition of the nucleus.
• C) The time is only statistically predictable, because our measuring instruments are not yet sufficiently precise.
• D) The time is precisely predictable for any particular isotope, regardless our knowledge of its precise state.
• E) The time is only statistically predictable, because of unavoidable uncertainties associated with quantum theory.

pH

A measure of the acidity or alkalinity of a solution, determined by the concentration of hydrogen ions, with lower values being more acidic and higher values more alkaline.
