2 more neutrons.
It is because living organisms absorb C14 from their environment. After death, they are no longer capable of absorbing any more C14. So, at the time of death, the C14 : C12 ratio is fixed. C14 undergoes radioactive decay (into C12) so the C14 : C12 ratio declines and that can be used as a measure of the time since death.
Isotopes have the same numbers of protons but different numbers of neutrons. One of the most common examples is carbon: C12 is the standard carbon atom, but C13 and C14, although still carbon atoms, have one or two extra neutrons.
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 =)
11 Carbon has atomic(proton) number 6. i.e it has 6 protons. There are three naturally occurring isotopes for carbon. They are C12 c13 and c14. among them c14 is radioactive. c12 has 6 protons and 6 neutrons. c13 has 6 protons and 7 neutrons. c14 has 6 protons and 8 neutrons. Similarly, c17 has 6 protons and 11 neutrons.
c12 is an element
Carbon is available in three isotopes, C12, C13 and C14. C12 is the most common.
3 - c12, c13 and c14
C12 and C14 are isotopes of the Element Carbon. C12 is the most abundant of all which is 99% of all the Carbon on earth while C14 is only 0.0000000001% (trace amount). C12 has a Atomic Number of 12. It has 6 Protons and 6 Neutrons. C14 has a Atomic Number of 14. It has 6 Protons and 8 Neutrons. C14 is radioactive in nature. It is used for carbon dating.
carbon exists as 3 naturally isotopes c12 c13 c14 as he number of neutrons increase in the isotope the nuclear charge
It is called an Isotope.... C12, C13, C14 is a classical example
It is because living organisms absorb C14 from their environment. After death, they are no longer capable of absorbing any more C14. So, at the time of death, the C14 : C12 ratio is fixed. C14 undergoes radioactive decay (into C12) so the C14 : C12 ratio declines and that can be used as a measure of the time since death.

isotopes. ex- c14,c12 are isotopes .proton same 6. neutrons are 8,6 respectively
with C14 atom
In Carbon-12, the most abundant form of Carbon, there are 6 Neutrons, 6 Protons and 6 Electrons. In Carbon-14, the radioactive isotope of Carbon used in Carbon Dating, has 6 Protons, 8 Neutrons and 6 Electrons.
Carbon has the atomic number 6. Its mass number (to the nearest integer value) is 12, and it has two isotopes, C12 and C14, the latter of which is radioactive.
