Three electron domains refer to the arrangement of electrons around a central atom in a molecule or ion. This can correspond to a trigonal planar geometry, where the electron domains are positioned at the corners of an equilateral triangle around the central atom. Examples of molecules with three electron domains include boron trifluoride (BF3) and ozone (O3).
In a molecule with 4 electron domains, the molecular geometry can be tetrahedral if all domains are bonded pairs or trigonal pyramidal if one domain is a lone pair. This arrangement follows the VSEPR theory, which predicts the shape of molecules based on the number of electron domains around the central atom.
In chemistry, 5 electron domains refer to the number of regions around an atom where electrons are likely to be found. This can correspond to a central atom surrounded by five bonding pairs or lone pairs of electrons. This configuration can result in different molecular geometries depending on the arrangement of these electron domains.
A molecule with 6 electron domains can have a trigonal bipyramidal molecular geometry. This means there are 5 atoms or groups surrounding the central atom with bond angles of 90° and 120°.
This is based upon the number of protons in the atom's [or ion's] nucleus: it's atomic number. Protons possess one positive charge, normally balanced or offset by the negative charge possessed by an electron.
There are five electron domains around the sulfur atom in SF4. This is due to the presence of one lone pair and four bonding pairs of electrons.

XeF2 has 3 electron domains around the central xenon atom. This includes 2 bonding domains and 1 non-bonding domain.
There are electron particles in O2 as well as in every thing in your body.
3 bondings + 1 electron pair = 4 (electron domains)
Because there are 2 bonded and 2 unbonded electron domains. since there are 4 electron domains, its original form would be a tetrahedral. however, for the molecular, you must remove to two unbonded domains, leaving the two domains as far apart from each other as possible

O2 ADDED: Not O2, but one atom of oxygen.
The lowest energy excited state electron configuration of O2 is 1s2 2s2 2p4. This configuration represents the two oxygen atoms in a triplet state where one electron is promoted from the 2p to the 2π* antibonding orbital.
