An orbital blowout fracture is a fracture or break in the small bones that make up your eye. The orbit, or eye socket, is the cavity of the skull that holds the eye. An orbital blowout can occur when an object strikes the orbit with blunt force. This injury is commonly the result of a fist, baseball or tennis ball that strikes the eye. The bony orbit's job is to protect the eyeball.
These orbitals are organized in concentric shells proceeding outward from the nucleus with an increasing number of subshells. The electrons in orbitals closest to the nucleus are held most tightly; those in the outermost orbitals are shielded by intervening electrons and are the most loosely held by the nucleus. As the electrons move about within this structure, they form a diffuse cloud of negative charge that occupies nearly the entire volume of the atom.
