What Is The Definition Of Isotope In Chemistry

Stable isotope one that does not transmute into another element with emission of.

What is the definition of isotope in chemistry. I so tōp a chemical element having the same atomic number as another i e the same number of nuclear protons but having a different atomic mass i e a different number of nuclear neutrons. What is an isotope. Isotopes are atoms that have the same atomic number and hence generally the same chemistry but different mass. The mass of a neutron is almost.

There are 275 isotopes of the 81 stable elements in addition to over 800 radioactive isotopes and every element has known isotopic forms. Isotope definition is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties. Elements are defined by the number of protons in the atomic nucleus. More than one type of daughter isotope may result.

Chemistry dictionary definition of isotope effect the effect on the rate or equilibrium constant of two reactions that differ only in the isotopic composition of one or more of their otherwise chemically identical components is referred to as a kinetic isotope effect see isotope effect kinetic or a thermodynamic or equilibrium isotope. For example when a carbon hydrogen bond is replaced by a carbon deuterium bond deuterium being. Apart from these some other common isotope examples include tin has 22 isotopes zinc has 21 known isotopes neon is a mix of 3 isotopes natural xenon consists of a mixture of 9 stable isotopes nickel has 14 known isotopes. Isotope one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties.

Any one of various forms in which the atoms of a chemical element can occur isotope in a sentence. Other articles where isotope effect is discussed. Radioactive isotope radioisotope. Here carbon 12 is a stable isotope whereas carbon 14 is mostly a radioactive isotope.

In addition to protons the atoms of nearly every element also contain neutrons. As an example when u 238 decays into th 234 the uranium atom is the parent isotope while the thorium atom is the daughter isotope. Isotope definition any of two or more forms of a chemical element having the same number of protons in the nucleus or the same atomic number but having different numbers of neutrons in the nucleus or different atomic weights. An atom is first identified and labeled according to the number of protons in its nucleus.

Every chemical element has one or more isotopes. The term isotope is form this topic is school chemistry or high school chemistry in the usa up to 14 16 when discussing the meaning and properties of isotopes in general as on this define isotope.
