In arsenic triiodide (AsI3), arsenic (As) typically has five valence electrons, while each iodine (I) atom has seven valence electrons. In the molecule, arsenic forms three covalent bonds with three iodine atoms, using three of its valence electrons. This leaves arsenic with two unshared electrons, which can be considered as one lone pair. Therefore, there is one ion pair of electrons associated with the arsenic in AsI3.
There are 2 lone pairs in TeO3^2-.
In phosphine (PH3), there are three lone pairs and three bonding pairs.
Germanium (Ge) has 2 lone pairs of electrons.
The Si has no lone pairs, but each F has 6 lone pairs. Thus 6 x 4 = 24 lone pairs, total.
