Explain an isotope
WebAn isotope is an atom of the same element that has different numbers of neutrons. A few examples of ions are Na+2 (cation) and F- (anion.) A few examples of isotopes are Uranium-235 and Carbon-13. ... Explain why there is a difference. An anion is a negatively charged ion that has gained more electrons than protons and added them to it's energy ... There are a couple of common ways to indicate isotopes: 1. 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 … See more Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons). Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope). … See more The term "isotope" was introduced by the British chemist Frederick Soddy in 1913, as recommended by Margaret Todd. The word means "having the same place" from the Greek words isos "equal" (iso-) + topos"place." … See more When radioisotopes undergo radioactive decay, the initial isotope may be different from the resulting isotope. The initial isotope is called the … See more Most stable isotopes don't undergo radioactive decay, but a few do. If an isotope undergoes radioactive decay very, very slowly, it may be termed stable. An example is bismuth … See more
