Radioactive decay of carbon isotopes can be use for?
to allow the correct amount of oxygen to enter and leave the substance
Why do scientist use radioactive dating?
To figure out how old something is based how long it takes elements in the sample to decay.
How do you use Radioactive dating in a sentence?
My nerdy brother wants to start a radioactive dating website! The use of radiometric, or radioactive, dating was initiated in 1907 by Bertram Boltwood.
What are atoms with the same number of protons and different numbers of neutrons called?
Isotopes have the same number of protons but a different number of neutrons. Different isotopes of a single element are on the same position on the periodic table of elements. The existence of isotopes was first suggested in 1913 by a radiochemist named Frederick Soddy.
What does carbordating mean?
Do you mean carbon dating? Carbon dating is a process that scientists use to try to ascertain the age of an item by analyzing the amount of a radioactive carbon isotope that is present in the item. Generally this is used to date biological items. Like, really old trees and stuff. The percent of the radioactive isotope in the specimen is accumulated to normal levels as the thing was alive, after it is dead it stops absorbing new carbon and thus by measuring the ratio of isotopes that are decaying we can determine the age of the item. (using the half-life of the radioactive isotope)
How do scientist use Radioactive Isotopes to find the absolute age of a rock?
Absolute dating is a radioactive isotope the geologist can use to learn the exact age of the rock.
How do you carryout radiometric dating?
By the use of isotopes of radioactive elements through the determination of their half life.
What two ways do scientist use fossils to determine the environmental changes?
its radioactive dating and relative dating
What of the use of isotopes in archeology?
One would use radioactive isotopes as to measure decay rates in an ancient piece (e.g. rock) to estimate its age. e.g. carbon dating
What would you use to do absolute dating of a rock layer?
There are several ways to do absolute dating of a rock layer. One of these is to use the radioactive decay of the isotopes that are naturally found in rocks.
Are there any types of nuclear medicine that doesn't use radioactive isotopes?
All nuclear medicine techniques use radioactive isotopes.
Radioactive decay of carbon isotopes can be use for?
to allow the correct amount of oxygen to enter and leave the substance

Can use radiometric dating on all minerals to tell their absolute age?
No, radiometric dating can only be used on certain minerals that contain radioactive isotopes. These minerals include zircon, potassium feldspar, and biotite, among others. Not all minerals contain radioactive isotopes, so radiometric dating cannot be applied to all minerals.
For what purpose do geologists use relative dating?
It remains a useful technique especially in materials lacking radioactive isotopes. Relative dating by biostratigraphy is the preferred method inpaleontology, and is in some respects more accurate
Scientists use the amount of radioactive isotopes found in rocks and fossils to calculate their ages this process is called?
the rock and the fossils are made out of lava stuff
