Atomic Orbitals

43.3K
An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.

Electron Orbital Model

71.8K
Orbitals are the areas outside of the atomic nucleus where electrons are most likely to reside. They are characterized by different energy levels, shapes, and three-dimensional orientations. The location of electrons is described most generally by a shell or principal energy level, then by a subshell within each shell, and finally, by individual orbitals found within the subshells.
The first shell is closest to the nucleus, and it has only one subshell with a single spherical orbital called the...

Hybridization of Atomic Orbitals I

66.0K
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

    Area of Science:

    • Oncology
    • Ophthalmology
    • Developmental Biology

    Background:

    • Teratomas are neoplasms originating from pluripotent embryonal stem cells.
    • These tumors contain elements from all three germinal layers (ectoderm, mesoderm, endoderm).
    • Intraorbital teratomas are exceptionally rare pediatric malignancies.

    Observation:

    • A case report of a female infant diagnosed with a primary intraorbital teratoma is presented.
    • The tumor presented with symptoms developing in the early months of life due to growing cystoid components.
    • Surgical intervention for intraorbital teratomas is often complex and carries a high risk of ocular damage.

    Findings:

    • The patient underwent a partial tumor resection.
    • Crucially, the surgical procedure successfully spared the eye globe.
    • Post-operative assessment confirmed the presence of retained visual functions.

    Implications:

    • This case demonstrates the feasibility of conservative surgical management for intraorbital teratomas.
    • Preservation of ocular structures and visual function is achievable even with complex orbital tumors.
    • Highlights the importance of tailored surgical approaches in pediatric orbital oncology.
