What is d orbital?
The d orbital is the orbital that only applies to the 3rd orbital and up and it contains 10 electrons.
The 3s orbital differs from 2s orbital in that it is?
The 2s orbital and 3s orbital both have the same spherical shape and can hold a maximum of two electrons of opposite spin. They only differ because the 3s orbital is further out from the nucleus than the 2s orbital, thus the 3s orbital has a higher energy value.
What is vacant d orbital?
vacant d orbital means an empty d orbital. For example, in nitrogen a d orbital is not allowed whereas in phosphorus a vacant d orbital is present.
What is diffrenec between inner orbital and outer orbital complex?
If inner d orbital is involved in hybridization, it is called inner d orbital complex. and if outer d orbital is involved in hybridization then it is called 'outer d orbital complex'.
The major difference between a 1s orbital and a 2s orbital is that?
the 2s orbital is at a higher energy level
What population groups tend to get orbital and periorbital cellulitis?
Periorbital cellulitis, which accounts for 85-90% of all ocular cellulitis, usually occurs in children under the age of five. Responsible for the remaining 10-15% of these infections, orbital cellulitis is most common in children over the age of five.

What are the symptoms of orbital and periorbital cellulitis?
People with periorbital cellulitis will have swollen, painful lids and redness, but probably no fever. About one child in five has a runny nose, and 20% have conjunctivitis. Conjunctivitis, also called pinkeye, is an inflammation of the mucous.
What is preseptal cellulitis?
Preseptal cellulitis (periorbital cellulitis) is infection of the eyelid and surrounding skin anterior to the orbital septum Preseptal cellulitis causes tenderness, swelling, and redness or discoloration (violaceous in the case of H. influenzae) of the eyelid. Patients may be unable to open their eyes, but visual acuity remains normal. Treatment is with antibiotics.
Is periorbital cellulitis contagious?
It is VERY contageous.
What is the treatment for orbital and periorbital cellulitis?
A child who has orbital or periorbital cellulitis should be hospitalized without delay. Antibiotics are used to stop the spread of infection and prevent damage to the optic nerve, which transmits visual images to the brain.
What is the most frequent cause of orbital cellulitis in children?
In children, Haemophilus influenzae type B frequently causes orbital cellulitis following a sinus infection.
What complications are associated with orbital cellulitis?
If diagnosed promptly and treated with antibiotics, most orbital and periorbital cellulitis can be cured. These conditions are serious and need prompt treatment. Infections that spread beyond the eye socket can cause.
Is orbital cellulitis contagious?
no
What are the symptoms of orbital cellulitis?
Infection of the tissues surrounding the eye causes redness, swollen eyelids, severe pain, and causes the eye to bulge out
What ages are most affected by cellulitis?
In case of periorbital cellulitis most affected are youngsters (cause bacteria HiB). In case of leg or arm cellulitis most affected are older patients(cause Staph or Strep bacteria). Cellulitis affects people of all ages.
