Atomic Radii and Effective Nuclear Charge03:08

Atomic Radii and Effective Nuclear Charge

63.5K
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells.

The Bohr Model

83.0K
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the...

Electronic Structure of Atoms

30.2K

An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the nucleus. Taking into account the wave–particle duality of electrons and the uncertainty in position around the nucleus, quantum mechanics provides a more accurate model for the atomic structure. It describes atomic orbitals as the regions around the nucleus where electrons of discrete energy exist, characterized by four quantum...

Atomic Nuclei: Nuclear Magnetic Moment

3.5K
All atomic nuclei are positively charged. When they have a nonzero spin, they behave like rotating charges. As a consequence of their charge and spin, these nuclei generate a magnetic field (B). This, in turn, gives rise to a magnetic moment (μ), which is randomly oriented in the absence of an external magnetic field. When an external magnetic field (B0) is applied, the magnetic moment vectors can align with the field or against it in 2 + 1 orientations. A hydrogen nucleus, which is just a...

The Quantum-Mechanical Model of an Atom

61.4K
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

Atomic Nuclei: Nuclear Spin State Overview

2.2K
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of one, the...

    Area of Science:

    • Atomic Physics
    • Quantum Mechanics
    • Nuclear Physics

    Background:

    • The common perception of Hantaro Nagaoka's Saturnian atom model is inaccurate.
    • Nagaoka's model is often visualized as a large nucleus with electrons orbiting closely, which is a misrepresentation.

    Purpose of the Study:

    • To correct the widespread misconception of Nagaoka's atomic model.
    • To establish Nagaoka's rightful place alongside Rutherford and Bohr in the history of atomic theory.
    • To highlight Nagaoka's early contributions to understanding nuclear structure through hyperfine interactions.

    Main Methods:

    • Comparative analysis of atomic models: Nagaoka's, Rutherford's, and Bohr's.
    • Examination of the Coulomb potential in atomic systems.
    • Review of historical scientific literature on atomic structure.

    Main Results:

    • Nagaoka's Saturnian model is mathematically equivalent to Rutherford's and Bohr's models due to the Coulomb potential.
    • The prevailing "giant core" interpretation of Nagaoka's model is erroneous.
    • Nagaoka's work predates and anticipates key concepts in nuclear physics.

    Conclusions:

    • Hantaro Nagaoka deserves recognition alongside Rutherford and Bohr for his foundational contributions to atomic modeling.
    • Nagaoka's insights into atomic structure were advanced for his time, including pioneering work on hyperfine interactions for nuclear studies.
