Atomic Orbitals

Atomic Orbitals

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.

Hybridization of Atomic Orbitals I

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...

The Energies of Atomic Orbitals

The Energies of Atomic Orbitals

In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions are also observed. The attractive and repulsive forces are dependent on the distance between the particles, as well as the sign and magnitude of the charges on the individual particles. When the charges on the particles are opposite, they attract each other. If both particles have the same charge, they repel each other.

Area of Science:

Anatomy
Orthopedics
Genetics

Background:

Wormian bones are accessory ossicles in the skull, arising from aberrant ossification centers.
Their etiology is linked to genetic and/or environmental influences.
While commonly found at cranial sutures, their presence in the orbit is infrequent.

Observation:

This report details a rare case of Wormian bones located within the orbit.
Orbital Wormian bones can mimic fractures on imaging studies.
These ossicles pose surgical risks, potentially causing injury if dislodged.

Findings:

The study presents a case of orbital Wormian bones, a rare anatomical variant.
Literature review confirms the rarity of Wormian bones in the orbital region.
Clinical implications include diagnostic challenges and surgical hazards.

Implications:

Recognizing orbital Wormian bones is crucial for accurate diagnosis and surgical planning.
Understanding their potential to simulate fractures aids in interpreting imaging.
Awareness of surgical risks associated with these bones can prevent intraoperative complications.
