  • Atom
    Smallest unit of matter, consisting of a nucleus surrounded by electrons arranged in shells, subshells, and orbitals.
  • Electronic Structure
    Arrangement groupings of electrons in shells, subshells, and orbitals, revealing their locations and behaviors.
  • Shell
    Main energy level around the nucleus, indicating the size and energy of electrons traveling in orbits.
  • Subshell
    Division within a shell, labeled s, p, d, or f, that defines the shape of regions where electrons are likely found.
  • Orbital
    Specific region within a subshell where a particular electron is most likely to be located, with defined orientation.
  • Electron
    Negatively charged particle found in orbitals, capable of spinning in two possible directions within its region.
  • Nucleus
    Central core of an atom, around which electrons travel in defined shells.
  • Energy Level
    Quantized state associated with a shell, determining the energy and distance of electrons from the nucleus.
  • Shape
    Geometric form of a region within a subshell, determined by the type (s, p, d, f) and influencing electron distribution.
  • Orientation
    Spatial arrangement of an orbital within a subshell, specifying how electron regions are directed in space.
  • Spin
    Intrinsic property of electrons, describing their clockwise or counterclockwise motion within an orbital.
  • s Subshell
    Type of subshell with a spherical shape, representing one possible region for electrons within a shell.
  • p Subshell
    Type of subshell with a dumbbell shape, offering three possible regions for electrons within a shell.
  • d Subshell
    Type of subshell with more complex shapes, providing five possible regions for electrons within a shell.
  • f Subshell
    Type of subshell with even more complex shapes, containing seven possible regions for electrons within a shell.
