What is different between an atom of 12C and an atom of 13C?
Asked in Atoms and Atomic Structure
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.

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

Asked in Chemistry, The Difference Between, Isotopes
What is the difference between an element and a isotope?
Isotopes are different forms of the element (they are therefore still elements). For example - Carbon has 15 known isotopes, the stable ones being 12C and 13C. All isotopes for the same element have the same number of protons, but a different number of neutrons. This means isotopes have different properties, such as different weights - but are all still the same element.

How many types of atoms are present in carbon dioxide?
What is the number of all subatomic particles in carbon?
In a 12C carbon atom, there are 6 protons, 6 neutrons, and 6 electrons. (98.8%) In a 13C carbon atom, there are 6 protons, 7 neutrons, and 6 electrons. (1.2%) In a 14C carbon atom, there are 6 protons, 8 neutrons, and 6 electrons. There are only trace amounts in Nature of 14C carbon which is radioactive and decays with a halflife of 5730 years Carbon-12, the most common isotope, has 6 Protons, 6 Electrons, and 6 Neutrons.
