Ammonia contains N and H atoms. There are 3 bonding pairs.
There are three bonds. So there are six bonding electrons
the lone pair on electron like nh3 make molecule good donor.
To determine the structural geometry of a molecule, structural pair geometry must be used. These are the amounts of pairs found surrounding a specific molecule, and they are unique to each type of atom.
there are three N-H bonds in ammonia and hence ammonia has three bonded pairs of electrons in addition, there is one lone pair of electrons on nitrogen
It has a total of 4 electron pairs. Electron geometry is tetra hedaral.
Ammonia is a polar molecule because the different electronegativity's of the nitrogen and the hydrogen molecules makes the hydrogen slightly positive and the nitrogen slightly negative. However there are 2 valance electons of the nitrogen atom which are not bonded to anything, which are called lone pairs. The lone pairs means that the ammonia molecule is not symmetrical therefore the electronegativity's do not cancel eachother, creating a polar molecule. ( The reason why the shape is no longer symmetircal is because lone pairs repel more than the bond pairs of the N-H, and essentially the bonding pairs are "squeezed" together, which accounts for the smaller than expected bond angle of 107 degrees)
There are a infinitely growing number of bond pairs between atoms.
the lone pair on electron like nh3 make molecule good donor.

There are four electron pairs. But there is only one lone pair.
ONE!
Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. They are also called Lewis dot diagrams, electron dot diagrams, and electron dot structures. See the link below for Lewis structure.
