Absolute dating is a radioactive isotope the geologist can use to learn the exact age of the rock.
None. Carbon dating is appropriate for remains of organic materials, not rocks.
well they put effort to succedd :)
It is not yet discovered since all of the uranium isotopes are having half life for several millions of years. We would be able to find it after atleast 700 millions of years.
yes
The number of protons defines an element - the number of neutrons isn't needed to find the identity of the element. All ions and isotopes with 44 protons is ruthenium. However, with the information about the neutrons, we know the specific isotope: 101Ru.
It is RADIOACTIVE. Very rare to find in a house.
Earths atmosphere
The same element can have different half-lives, for different isotopes. You can find a list at the Wikipedia article "List of radioactive isotopes by half-life". This list is NOT complete; a complete list would have about 3000 nuclides (that is, isotopes).

Answer : When the isotopes decay, scientists can find out how old the rock is depending on the radioactive isotope's half-life. Explanation: Radioactive isotopes are unstable and will decay. For example, when humans die carbon-14 decays. The isotopes will decay into a stable isotope over time. Scientists can tell how old the rock was from looking at the radioactive isotope's half-life, which tells them how long it would take for there to be half the radioactive isotope and half the stable isotope. At the next half-life there will be 25% of the radioactive isotope and 75% of the stable isotope. At the next half life there will be 12.5% radioactive and 87.5% stable. Example: Carbon-14 is a radioactive isotope with a half life of 5,730 years. How old would carbon-14 be when there is 75% carbon-14 in the rock? 75% is half of the time before the half-life, so it would be 2,365 years. Hope this helps. Half life helps scientists find how much the isotope has decayed and the age of the rock.

The atoms that are radioactive are those with unstable nuclei. There is no easy way to tell which is which, so the isotope has to be looked up. All elements have at least some radioactive isotopes. There are 36 elements for which all radioactive isotopes are synthetic or fission products, so for practical purposes, there are no radioactive isotopes of them in nature, except where introduced by human activity. They include most of the common elements we find in nature, but not all. There are 44 elements that are found as stable isotopes, but at least traces of radioactive isotopes are found in nature. Among these are hydrogen, carbon, sodium, silicon, chlorine, and potassium, all of which are necessary for life. Radioactive potassium, in particular, is present as 0.012% of all potassium. For another group of elements, including technetium, promethium, and all with atomic numbers of 83 (bismuth) or more, there is no isotope that is stable.
yes
its not from radioactivity its from carbon dating
yes they can they did it with aborinies
You measure the amount of radioactive decay that is present in certain elements that were present when the rock formed from melt.
scientists use carbon14 and potassium argon to find absolute age of rock
No the element Mercury is not Radioactive. None of the mercury ordinarily found in nature is radioactive. Like all elements, there are synthetic radioactive isotopes of mercury.
