Every pair of electrons on the central atom (S) of the Lewis structure of SF6 is shared by an F atom, so therefore there are no lone pairs on the central atom.
There is only one bond. It is on the N atom.
3 non bonding pairs. Fluorine is in group 17 and has an outer shell configuration of 2s2, 2p5. Just one electron in the fluorine atom is unpaired the other 6 are paired
10
3 bonds
3 bonding pairs and one lone pair or non-bonding pair
two, six

The answer is 1. This is because the only atom with lone paires is phosphorus and it only has 1.
Each iodine atom in a molecule of carbon tetraiodide has three non-bonding pairs of electrons.
you have 5 binded elektron pairs, and one free pair
Every pair of electrons on the central atom (S) of the Lewis structure of SF6 is shared by an F atom, so therefore there are no lone pairs on the central atom.
IN an ammonia molecule the central nitrogen atom has 3 three bonds.
it will form three bonding
There is only one bond. It is on the N atom.
One valence electron
