No lone pairs
There are 1
If an atom has five valence electrons, it will have one lone pair of electrons.
two bonds and eight lone pairs

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.
0
The Central atom has no lone pairs in CH4
ONE!
Boron trichloride is an inorganic compound that is a valuable reagent in organic synthesis. It has zero lone pairs on the central atom.
you have 5 binded elektron pairs, and one free pair
The lone pairs are on the bromine atom- 3 in all.
There are three lone pairs present in chlorine atom
One lone pair. The central atom is N (nitrogen) which has 5 valence electrons. Three of them are shared with 3 hydrogen atoms, leaving 2 electrons (1 lone pair) on the N.
Two lone pair on the central selenium and three lone pairs on each chlorine. So total of eight lone pairs.
No lone pairs on the N in the nitrate anion (NO3^-)
