Radiometric dating is not useful on sedimentary rocks because they are formed from the accumulation of sediments, which may contain elements with different ages. The process of sedimentation can also disturb the isotopic composition.
Carbon-14 dating would be most useful in dating bones found in Egyptian tombs, as it can date organic materials up to about 50,000 years old. Bones contain organic material which can be tested for radiocarbon levels to determine their age accurately.
You can't date all minerals using the radiometric dating method because not all minerals have radioactive isotopes. In addition, the parent and daughter isotopes must remain together in a rock to use them to determine the rock's age. Because sedimentary rocks contain fragments of many rocks that could be different ages, radiometric dating is less useful for dating sedimentary rock. This technique is primarily used to date igneous rocks.
Isotopes can be used in radiometric dating to determine the age of rocks. By measuring the ratio of parent and daughter isotopes in a rock sample, scientists can calculate how long it has been since the rock formed. This method is particularly useful in dating rocks that are billions of years old.
So you can find out how old your mom is. Roast!!!

Radiometric dating is least useful for dating sedimentary rocks because they are formed from the accumulation of sediments, making it difficult to determine the original isotopic composition.
Radiometric dating is less useful for dating sedimentary rocks because they are made up of material that has been transported and deposited from other sources, making the age of the sedimentary rock different from the age of the material within it. Igneous rocks directly crystallize from magma and accurately retain the age of their formation through radiometric dating.

CARBON DATING The most common fossil dating techniques are radiometric dating techniques. Radiometric dating uses knowledge of the decay rates of unstable ( radioactive ) nuclei to determine, by comparison with the proportion of stable nuclei in a fossil sample, the date of the introduction of the radioactive material into the live organism, especially if the isotope was ingested while the organism was alive.

No, not all radioactive isotopes be used in radiometric dating. Some have very very short half lives and would entirely disappear before any useful period of time passed.

Protactinium is not a useful element.The ratio Pa-231/Th-230 in natural sediments is used to radiometric dating up to 175 000 years ago.
Radiocarbon dating is not typically used to determine the age of the Earth because it can only accurately date organic materials up to around 50,000 years old. Other dating methods, such as radiometric dating of rocks and minerals, are used to estimate the age of the Earth, around 4.5 billion years.
Uranium is most useful for radiometric dating in igneous rocks, such as granite or basalt, and in metamorphic rocks that have undergone high temperature events. These types of rocks are typically rich in uranium and provide reliable age information for geologists. Sedimentary rocks are generally less suitable for uranium dating due to the potential for uranium to be remobilized.
