Isotopes of an element have the same number of electrons and the same electron configuration. What is the difference between an elephants bottom and a post. Isotopes of an element have the same chemical properties but different physical properties.

An isotope is named after the element and the mass number of its atoms. The Physical Properties of Isotopes. For example carbon-12 is an isotope of carbon with a mass number of 12.

The physical properties of isotopes in a particular element vary from each other. 3 CARBON-1414C -----It contains eight neutrons in its nucleus. Among the hydrogen isotopes the physical properties of H2 HD and D2 are included in the Aspen Plus however HT DT and T2 are not included.

Other than protium ordinary hydrogen helium-3 is the only stable isotope of any element with more protons than neutrons. This is the most common isotope. Isotopes of an element have different masses.

Nature 95 78 1915. Isotopes have similar chemical properties because isotopes of an element have same number of electrons as an atom of that element owing to same chemical properties. The artificial isotopes of a chemical element have the same properties as the natural ones and also a similar metabolic activity.

Hydrogen isotopes are H2 HD D2 H2 HD D2 HT DT and T2. So different isotopes of an element show different physical properties. On the other hand heavy isotopes have large masses and.

An isotope is named after the element and the mass number of its atoms. An isotope is one of two or more forms of the same chemical element. Many physical properties eg melting point boiling point density etc depend upon the atomic mass.

Because the number of electrons in an atom and its isotopes are the same the chemical properties of an isotope are similar to that of the parent atom. This is because the physical properties of any isotope depend on the mass. Atoms of the same elements with different atomic masses This work is licensed under a Creative Commons Attribution-Noncommercial-Share Alike 20 UK.

289 Zeilen Many important properties of an isotope depend on its mass. The mass of each isotope of a single element varies from one another. Helium-3 was discovered in 1939.

It is the heaviest isotope after 12C. We make use of the fact that isotopes have different physical properties. Isotopes of the same element have different physical properties melting points boiling points and the nuclei of some isotopes are unstable and radioactive.

This isotope is unstable and highly radioactive. Hence they show different physical properties. Helium-3 3He see also helion is a light stable isotope of helium with two protons and one neutron the most common isotope helium-4 having two protons and two neutrons in contrast.

England Wales License Frederick Soddy Nobel Prize Chemistry 1921 3. The total number of. All three isotopes of.

Quantitative dissimilarities may occur since differences in the mass numbers may result in different mass in the diffusion and dissociation constant. So the properties which depend upon the atomic mass should be different for different isotopes. The physical properties of isotopes may differ from each other.

Chemical Properties of Radioactive Substances. Generally the physical properties are dependent on the atomic mass and. The number of electrons present inside an atom or element determines the chemical properties of the atom or element.

For example carbon-12 is an isotope of carbon with a mass number of 12. However they have different number of neutrons which affects the mass number. All three isotopes of.
