Question
Use the following chart to answer this question. The chart shows uranium-235 with the daughter isotope of lead-207 and the half-life is 710 million years. The second option is potassium-40 with a daughter isotope in 1.3 billion years. The last option is carbon-14 with a daughter isotope of nitrogran-14 in 5730 years. If an archeologist claimed to have found an artifact from the early bronze age in Egypt (around the year 3000 BC), which isotope would be the most effective in examining it?
A.Potassium-40 would be most effective.
B.Carbon-14 would be most effective.
C.Uranium-235 would be most effective.
D.All three isotopes would be equally effective.

Answer - D (All three isotoes would be equally effective)
Because traces of all isotopes will be present in given arifact since all isotopes have half life more than 5000 years
