Isotope - Wikipedia
Isotopes are two or more types of atoms that have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), and that differ in nucleon numbers (mass numbers) due to different numbers of neutronsin their nuclei. While all isotopes of a given element have almost the same chemical properties, they have different atomic masses and physical prop…

DOE Explains...Isotopes | Department of Energy
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6.

Isotope - an overview | ScienceDirect Topics
Isotopes. An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

Isotope Definition and Examples in Chemistry
Dec 14, 2008 · Isotope Notation. List the mass number of an element after its name or element symbol. For example, an isotope with 6 protons and 6 neutrons is carbon-12 or C-12. An isotope with 6 protons and 7 neutrons is carbon-13 or C-16. Note the mass number of two isotopes may be the same, even though they are different elements.

Isotope Definition & Meaning | Dictionary.com
Isotopes are distinguished from each other by giving the combined number of protons and neutrons in the nucleus. For example, uranium 235 is the isotope of uranium that has 235 protons and neutrons in its nucleus rather than the more commonly occurring 238. All elements have isotopes.

What are isotopes in simple terms?
The definition of an isotope is an element with similar chemical make-up and the same atomic number, but different atomic weights to another or others. An example of an isotope is Carbon 12 to Carbon 13. YourDictionary definition and usage example. "Isotope.".

What are examples of isotopes and their uses?
Uses of Stable Isotopes. Scientists performing environmental and ecological experiments use stable isotopes of oxygen, hydrogen, sulfur, nitrogen and carbon. For example, in geochemistry, scientists study the chemical composition of geological materials such as minerals and rocks.

What are the common isotopes?
Common stable isotopes include 2H/H, 18O/ 16O, and 13C/ 12C. These isotopes occur naturally in the environment, but their natural abundance differs with different environmental conditions.

What do isotopes look like?
Isotopes have different mass because of differing numbers of neutrons. However properties like color, malleability, chemical reactivity, taste, etc are strongly determined by the electron arrangement, which is not effected by having different numbers of neutrons.
