What is an Isotope? ChemTalk
Chemical and molecular properties A neutral atom has the same number of electrons as protons. Thus different isotopes of a given element all have the same number of electrons and share a similar electronic structure. Because the chemical behavior of an atom is largely determined by its electronic structure, … Meer weergeven Isotopes are distinct nuclear species (or nuclides, as technical term) of the same element. They have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence … Meer weergeven An isotope and/or nuclide is specified by the name of the particular element (this indicates the atomic number) followed by a hyphen and … Meer weergeven Radioactive isotopes The existence of isotopes was first suggested in 1913 by the radiochemist Frederick Soddy, based on studies of radioactive Meer weergeven The atomic mass (mr) of an isotope (nuclide) is determined mainly by its mass number (i.e. number of nucleons in its nucleus). … Meer weergeven A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example carbon-13 with 6 protons and 7 neutrons. The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over … Meer weergeven Some isotopes/nuclides are radioactive, and are therefore referred to as radioisotopes or radionuclides, whereas others have never been observed to decay radioactively … Meer weergeven Elements are composed either of one nuclide (mononuclidic elements), or of more than one naturally occurring isotopes. The unstable (radioactive) isotopes are either primordial or postprimordial. Primordial isotopes were a product of Meer weergeven WebElectrons and Electron Configuration. The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of … mane stream app
