While studying some sedimentary rocks in your field area, you find a mineral with rhombohedral cleavage that reacts with hydrochloric acid. Isotopes of the same element dont usually have the same properties. Each atom has a charged sub-structure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons. color Which statement is correct for the nucleus of any atom? No "disadvantages" but limitations instead: mass spectrometry will not tell you anything about a structure directly. Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13). 15. Isotopes are the same element with different numbers of protons and different numbers of neutrons. D They must have the same number of protons in their nuclei. Is it true that an isotope of an atom with a larger number of neutrons is larger than an isotope of the same atom that contains fewer neutrons? Carbon-12 is stable, meaning it never undergoes radioactive decay. Now, let us discuss each statement or property about isotope in the given options: Which of the following statements about isotopes is NOT correct? They have different numbers of neutrons. The net charge is not included for neutral atoms, as in the notation for hydrogen-, An isotope's mass number is closely related to its, Another term that students often might find confusingly similar to atomic mass and mass number is, There are two stable isotopes of chlorine: chlorine-, Let's think more about the average atomic mass of chlorine. hardness What is the atomic number and the mass number of an isotope of lithium containing 3 neutrons? Im also learning about this, so dont take my word for it, but I think that the electrons are only supposed to knock off one electron from the atom/molecule sample. C. They have essentially the same chemical properties. { "4.01:_Cutting_Aluminum_until_you_get_Atoms" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.02:_Indivisible_-_The_Atomic_Theory" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.03:_The_Nuclear_Atom" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.04:_The_Properties_of_Protons_Neutrons_and_Electrons" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.05:_Elements-_Defined_by_Their_Number_of_Protons" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.06:_Looking_for_Patterns_-_The_Periodic_Table" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.07:_Ions_-_Losing_and_Gaining_Electrons" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.08:_Isotopes_-_When_the_Number_of_Neutrons_Varies" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.09:_Atomic_Mass_-_The_Average_Mass_of_an_Elements_Atoms" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "01:_The_Chemical_World" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "02:_Measurement_and_Problem_Solving" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "03:_Matter_and_Energy" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "04:_Atoms_and_Elements" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "05:_Molecules_and_Compounds" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "06:_Chemical_Composition" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "07:_Chemical_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "08:_Quantities_in_Chemical_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "09:_Electrons_in_Atoms_and_the_Periodic_Table" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "10:_Chemical_Bonding" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "11:_Gases" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "12:_Liquids_Solids_and_Intermolecular_Forces" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13:_Solutions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "14:_Acids_and_Bases" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15:_Chemical_Equilibrium" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "16:_Oxidation_and_Reduction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "17:_Radioactivity_and_Nuclear_Chemistry" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "18:_Organic_Chemistry" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "19:_Biochemistry" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, 4.8: Isotopes -

The Average Mass of an Elements Atoms, status page at https://status.libretexts.org. Most scientists cannot tell you how many isotopic forms exist unless they consult an isotopic table. It does not account for isotopes: As per Dalton's atomic theory, all atoms of an element have identical masses and densities. Because the electron structure is the same isotopes have the same chemical properties.
