  2. Chemical decomposition - Wikipedia

    en.wikipedia.org/wiki/Chemical_decomposition

    H 2 CO 3 → H 2 O + CO 2. Other carbonates will decompose when heated to produce their corresponding metal oxide and carbon dioxide. [5] The following equation is an example, where M represents the given metal: MCO 3 → MO + CO 2. A specific example is that involving calcium carbonate: CaCO 3 → CaO + CO 2. Metal chlorates also decompose ...

  3. Rutherford model - Wikipedia

    en.wikipedia.org/wiki/Rutherford_model

    Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect. Rutherford's new model [1] for the atom, based on the experimental results, contained new features of a relatively high central charge concentrated into a very small ...

    en.wikipedia.org/wiki/Radionuclide

    This radiation is registered and the chemical composition of the sample can be determined from the analysis of the measured spectrum. By measuring the energy of the characteristic radiation lines, it is possible to determine the proton number of the chemical element that emits the radiation, and by measuring the number of emitted photons , it ...

  8. Rutherford scattering experiments - Wikipedia

    en.wikipedia.org/wiki/Rutherford_scattering...

    The prevailing model of atomic structure before Rutherford's experiments was devised by J. J. Thomson. [1]: 123 Thomson had discovered the electron through his work on cathode rays [2] and proposed that they existed within atoms, and an electric current is electrons hopping from one atom to an adjacent one in a series.
