Question

question 5 (multiple choice worth 2 points) (02 02r mc) what characteristic of carbon - 14 makes it useful for determining the age of organic materials? it can bond to itself. it decays in a set pattern. it is found in all substances. it can bond to other elements

Explanation:

Carbon - 14 is a radioactive isotope. Radioactive isotopes decay over time at a known rate (decays in a set pattern). This property is used in radiocarbon dating to determine the age of organic materials. The other options are incorrect: Carbon - 14 is not found in all substances (e.g., inorganic materials may not have it), while the ability to bond to itself or other elements is a property of carbon in general, not specifically what makes C - 14 useful for age determination.

Answer:

It decays in a set pattern.
