If asked "What is an isotope ?" in GCSE Chemistry, a more detailed answer is required using one of the definitions below:Definitions of an isotope: Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Another way to say the same ...
What is the isotope of fluorine? Fluorine: Fluorine is a chemical with nine protons. It is one of the most reactive chemical elements because it readily accepts electrons in order to form ionic compounds. Answer and Explanation:1 There are 18 known isotopes of fluorine, ranging from fluorine-...
Beyond a certain point, however, there is no configuration that provides a stable nucleus. None of the elements heavier than lead have any stable isotopes. Too many neutrons can also make an isotope unstable. For example, the commonest form of hydrogen has one proton and no neutrons, but ...
Synonyms Being; Brillat-Savarin; Feuerbach; Food; Healthy eating; Identity Introduction While it is possible to trace the roots of the phrase "you are what you eat" to early Christianity where the body and the blood of Jesus Christ were represented by bread and wine (Gilman 2008 ), the phr...
Medical radioisotopes such as iodine also lie outside what is known as the band of stability, but, in this case, they offer beneficial characteristics. Iodine-131 has four extra neutrons than its stable counterpart, and has a half-life of eight days. Since iodine can be safely ingested, it...
Technically, we too are radioactive, as our bodies have very trace amounts of the radioactive isotopes of potassium and carbon. Radioactivity is everywhere, and life forever remains indebted to it for keeping our Earth’s core broiling and ensuring that we are protected under a cozy magnetic ...
What are the stable isotopes of silicon? What is the mass number of an oxygen atom with 7 neutrons? What is the mass in kilograms of a single atom of carbon? What is the mass number of an element equal to? What is the mass of an electron in AMU?
There are five tungsten isotopes appearing in nature, and their half-lives are very long, so they can be regarded as stable isotopes. All these isotopes can be transformed into hafnium by alpha decay. The measurable half-life is 180W, and its half-life is 1.8×1018 years. The natural dec...
(Delphinus delphis) occur off Argentina coastline from 36°S to 42°S, but nothing is known about latitudinal changes in diet. A stable isotope analysis has been performed on three short-beaked common dolphins groups: Buenos Aires group (n = 20), Golfo San Matías inshore group (n = 24)...
