What are isotopes? To complicate things a bit more, we sometimes find atoms of a chemical element that are a bit different to what we expect. Take carbon, for example. The ordinary carbon we find in the world around us is sometimes called carbon-12. It has six protons, six electrons, ...

Isotopes are atoms of the same element that have a different number of neutrons. Neutrons are subatomic particles that make up the nucleus with protons. Protons never change between atoms of the same element and are the defining feature that makes an atom part of an element....
Isotopes are different forms of the same element. They have the same number of protons and electrons, but are different in the number of neutrons. As an example, consider the three isotopes of Candium. M&Ms, Skittles, and Reese's Pieces. They are all types of Candium with only one pro...

While light carbon isotopic compositions are consistent with biologically produced organic matter, alternative non-biological sources that might also explain the data have not been given thorough consideration. A review of the isotopic composition of potential non-biological sources of reduced carbon to ...
This helps me understand it better than how the teacher said it, because she just reiterates from the textbook but you guys at wisegeek really help explain it. Thanks! WiseGeek, in your inbox Our latest articles, guides, and more, delivered daily. ...
