Carbon 12 and carbon 14 are atoms of carbon, different isotopes of the element. Carbon owes its chemical identity, indeed, its elemental identity, to the number of protons in its nucleus. There are 6 of them. No more, no less. Carbon 12 has 6 protons and 6 neutrons. Carbon 14 has 6 protons and 8 neutrons. Carbon 14 has fewer protons than neutrons.

The following atoms are all variations of the element carbon. 12c 13c and 14c. what are theses variations called?
The following atoms are all variations of the element carbon 12C 13C 14C what are these variations called isotopes. Isotopes are variants of a particular chemical element.
How many proton and electrons and neutrons are there for carbon?
A carbon atom always contains six protons. In nature, carbon most commonly has six (12C, carbon-12), seven (13C, carbon-13) or eight (14C, carbon-14) neutrons. However, man-made isotopes of carbon contain as few as two neutrons (8C) or as many as sixteen (22C). Thirteen of the fifteen isotopes of Carbon (i.e. all except 12C and 13C) are radioactive. In addition to neutrons and protons, a carbon atom always has six electrons in orbits around the nucleus.
What is the mass 1 mole of carbon?
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.
How many atoms are in 0.615 moles of 13C?
.385 moles of atoms are in 5.00 of 13c. 5/13 = 0.385 mol
How many moles of atoms are in 9.00g of carbon 13?
Formal set up. ( Avogadro's number appears as form of 1 here ) 9.00 grams 13C (1 mole 13C/13.00 grams)(6.022 X 1023/1 mole 13C)(1 mole atoms 13C/6.022 X 1023) = 0.692 mole of 13C atoms ====================
Does 12C have fewer neutron than 13C?
Yes. Both carbon atoms have 6 protons. However, the 12C atom has 6 neutrons while the 13C atom has 7 neutrons :)

What are the isotope of carbon?
The most important is carbon-12.
The number of neutons in C is?
Common Isotopes of Carbon are 12C (6 neutrons), 13C (7 neutrons), and 14C (8 neutrons).
What does 13c and 11c mean for a snowboard?
Snowboard sizes for kids boots go from the smallest 11c, 12c, 13c, than goes to 1-15. The 1-15 sizes includes children through adult sizes. As for what the c indicates I believe its stands for child...not 100% sure though.

Isotopes 12C 13C and 14C all behave the same chemically because they?
All have the same nuclear charge and consequently the same electron configuration.
Is carbon 12 associated with fossil fuel burning?
Yes, you might have heard, which lead you to ask this question. I remember seeing graph's of how much and what time frame Carbon 12 has been put into are atmosphere. Here is one website that has a good explanation about it, all I did was type carbon 12 released from burning fossil fuels. http://www.realclimate.org/index.php/archives/2004/12/how-do-we-know-that-recent-cosub2sub-increases-are-due-to-human-activities-updated/ And here is a short passage from that website... Another, quite independent way that we know that fossil fuel burning and land clearing specifically are responsible for the increase in CO2 in the last 150 years is through the measurement of carbon isotopes. Isotopes are simply different atoms with the same chemical behavior (isotope means "same type") but with different masses. Carbon is composed of three different isotopes, 14C, 13C and 12C. 12C is the most common. 13C is about 1% of the total. 14C accounts for only about 1 in 1 trillion carbon atoms. CO2 produced from burning fossil fuels or burning forests has quite a different isotopic composition from CO2 in the atmosphere. This is because plants have a preference for the lighter isotopes (12C vs. 13C); thus they have lower 13C/12C ratios. Since fossil fuels are ultimately derived from ancient plants, plants and fossil fuels all have roughly the same 13C/12C ratio - about 2% lower than that of the atmosphere. As CO2 from these materials is released into, and mixes with, the atmosphere, the average 13C/12C ratio of the atmosphere decreases
How do you get proton decoupled spectra of 13C NMR?
There should be a button that lets you do this very easily. There is on a Brukker 400MHz NMR.
How many protons does carbon 12 have?
If the element in question is carbon, it has 6 protons, whether it's 12C, 13C, 14C, or any of its other 12 known isotopes.
How many types of atoms are present in carbon dioxide?
Carbon dioxide: CO2 Atoms of oxygen (16O, 17O, 18O) and atoms of carbon (12C, 13C, 14C).
What is the difference between proton and 13C for NMR?
Proton is an elementary particle (hydrogen nucleus) with the mass of approx. 1. Carbon-13 is a carbon natural isotope with the mass of approx. 13.
