If an atom has five valence electrons, it will have one lone pair of electrons.
you have 5 binded elektron pairs, and one free pair
Se belongs to oxygen family so it has six valence electrons, in SeF4 there are four covalent bonds so four electrons of Se are unpaired so there is only one lone pair of electrons on Se atom. 26
Because i has 6 electron pairs it is octahedral
Yes there is a nonzero dipole moment since it is a square pyramid (molecular geometry) and has a lone pair.

IF5
chemical bonding
Iodine hexafloride
IF5 is considered a type of polar molecule. It is a polar molecule because it can have dipole moments due to uneven charges.
iodine pentafluoride
