What is it called when a atom with the same number of proton but different number of neutron?
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.
The half-life of carbon-14 is 5730 years. How long will it take for the number of carbon-14 nuclei in a sample to drop to a quarter of the original number?
It will take two half-lives for the number of carbon-14 nuclei to drop to a quarter of the original number. Since the half-life of carbon-14 is 5730 years, it will take 2 * 5730 years = 11460 years for this to occur.
What is the c-14 c-12 ratio used to date once living organisms?
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.
How many neutrons does carbon-17 have?
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.
Is c12 a compound or element?
C12 is an isotope of the element carbon. It is not a compound since compounds are formed when two or more different elements chemically combine.
Atomic nomber of carbon?
Carbon is available in three isotopes, C12, C13 and C14. C12 is the most common.
How many isotopes dose c have?
3 - c12, c13 and c14
What is the difference between c 12 and c 14?
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.
An atom of an element is electrically neutral becaue the?
carbon exists as 3 naturally isotopes c12 c13 c14 as he number of neutrons increase in the isotope the nuclear charge

What are atoms of the same number of protons but different number of neutrons classified as?
isotopes. ex- c14,c12 are isotopes .proton same 6. neutrons are 8,6 respectively
What isotope serves as the current standard for the atomic mass scale?
with C14 atom
What is the number of neutrons in one atom of carbon?
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.
The half-life of carbon-14 is 5730 years. How long will it take for the number of carbon-14 nuclei in a sample to drop to a quarter of the original number?
It will take two half-lives for the number of carbon-14 nuclei to drop to a quarter of the original number. Since the half-life of carbon-14 is 5730 years, it will take 2 * 5730 years = 11460 years for this to occur.

Are all atoms with fewer neutrons than protons radioactive?
Uranium has 29 known isotopes and isomers (3 natural and 26 artificial). Two other isotopes are not still confirmed. For all elements heavier than Bismuth, all their isotopes are radioactive.
Is c12 a molecule?
Carbon 12 It has the atomic number of 12
