1.Carbon-14 is a radioactive isotope. What is an isotope?
What is the approximate half-life of carbon-14?
Isotopes of an element have the same number of electrons and protons but a different number of neutrons.
The half life of C-14 is approximately 5,700 years. You can look up the exact half life by Googling it. You could also Google isotopes and get the definition from the web. In fact, at least half the questions I answer here can be found on the internet through Google.
an element is determined by the number of protons in its nucleus.
In the case of carbon, that is 6.
The stable Carbon-12 also has 6 neutrons, making its atomic mass number 6+6=12
Radioactive Carbon-14 has 8 neutrons instead of 6.
An isotope is a form of an element with a different number of neutrons from the most common form.
Now go google carbon-14 (and isotope, while you're at it!) and you can find its half-life and how it is used.
thank you!(
To answer the first question: An isotope is a variant of an element that has the same number of protons but a different number of neutrons in its nucleus. This difference in the number of neutrons results in isotopes having different atomic masses.
Now, to answer the second question: The approximate half-life of carbon-14 is 5730 years.
The half-life of a radioactive isotope is the time it takes for half of the original sample to decay or undergo radioactive decay. In the case of carbon-14, after approximately 5730 years, half of the initial amount of carbon-14 will have decayed. This decay occurs through the emission of radiation, specifically beta particles, which results in the conversion of carbon-14 into a stable nitrogen-14 isotope.
