What is the isotope and example of isotope?
Isotopes are different types of atoms of the same element. These isotope will have the same atomic number (protons), but will differ in number of neutrons. An example of an isotope: carbon, carbon12 is the elemental form, carbon14 is an isotope of Carbon ...

What are radioactive isotopes?
A radioactive isotope is a form of an element that is unstable and eventually decays into a different element. For example, most Carbon has 6 protons and 6 neutrons, and is stable. This is called Carbon12. Carbon14 with 6 protons and 8 neutrons, is unstable and decays by releasing a beta particle from its nucleus to become a stable isotope, Nitrogen14. which has 7 protons and 7 neutrons. That refers to an isotope that is unstable - the atoms will decay after a...
Asked in Physics, Chemistry, Fossils
An artifact is found that some are claiming is 30000 years old 3.1 percent of the original carbon14 is present The halflife of carbon14 is 5730 year?
Yes, but the dating is only off a little (500 years or so).

Why is carbon 14 used for radioactive dating?
Because all living things contain Carbon and a small portion of that Carbon is the radioactive isotope Carbon14. There would be little point in using other radio active isotopes which aren't naturally present in things which need to be dated. ...
What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years. ...
Asked in Chemistry, Isotopes
What is the stable isotope that is formed by the breakdown of a radioactive isotope?
That's called a daughter isotope, or a daughter product. (The original isotope that decayed is the parent isotope.) ...
Asked in Physics, Chemistry, Nuclear Physics
Carbon14 has a half-life of 5730 years How long does it take a 200gram sample of carbon14 to decay to a mass of 100 grams?
5370 years. A half-life is how long a radioactive object takes for half of all its atoms to become new elements. 100 is half of 200 =) ...
Asked in Nuclear Physics, Physics, Chemistry
Carbon14 has a half life of 5730 years How long does it take a 200 gram sample of carbon14 to decay to a mass of 100 grams?
Forever and a day. 200g of C14 will never decay to a mass of 100g. C14 decays to C12. The final product of the decay of 200g C14 is ~172g C12. ...
How is an isotope and mass number related?
An isotope and a mass number are related because each isotope has a specific mass number. Tritium, an isotope of Hydrogen, has a mass number of 3, so it can be said that an isotope has a mass number, no matter what the isotope is. ...
Does the carbon14 have more protons neutrons or electrons than carbon12?
It has the same number of protons and electrons, but two more neutrons.
