I think this was based on the construction of Nitrogen.
Nitrogen has an atomic number of 7.
It has 2 electrons in it's first shell, leaving
5 electrons in it's outer shell.
It wants to fill the outer shell with 8 electrons so it can make 3 bonds with hydrogen.
So, one gets NH3. With each of the 3 electrons from Hydrogen bonded with a single electron from Nitrogen.
So, of the 5 electrons in Nitrogen's outer shell, 3 of them are bonded to Hydrogen, and 2 of them are just kind of sitting there.
This actually gives the Ammonia a tetrahedron shape. See the structure from Wikipedia:
http://en.wikipedia.org/wiki/Ammonia
With the two polar electrons up at the top.
Also, see the Wikipedia article on orbital hybridization.
http://en.wikipedia.org/wiki/Orbital_hybridisation
with four sp3 orbitals.
This extra sp3 orbital (pair of electrons) tends to attract a fourth Hydrogen (H+) ion.
Thus Ammonia (NH3) is polar, and acts as a base by attracting H+ ions, with its conjugate acid being Ammonium (NH4+)

Is h2 polar or nonpolar molecule?
H2S is considered a polar molecule. Its construction allows it to have dipoles and dipole moments, which makes it polar.
Is IF5 polar or non polar?
IF5 is considered a type of polar molecule. It is a polar molecule because it can have dipole moments due to uneven charges.
Why is ammonia considered a polar molecule?
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)
Is ammonia a polar compound?
No, ammonia is non-polar.
What type of bond holds ammonia?
When each molecule is considered, only three covalent bonds are there. When liquid ammonia is considered, there are hydrogen bonds between the molecules.
Is H plus polar or non polar?
If you think to ammonia molecule, this is polar.
Is ammonia mlecule NH3 more polar than water molecule?
no, water is more polar than ammonia.
Is ammonium hydroxide polar or non polar?
Ammonium chloride is polar, it dissolves in water.
What is an example of a polar molecule other than water?
ammonia
Is ammonia is soluble in water or a polar molecule?
Ammonia form in water ammonium hydroxide - NH4OH.
Why is a water molecule considered to be a polar molecule?
A water molecule is considered a polar molecule because of its shape. That is, its poles contain opposing charges, the positive and negative charge.
Is NH3 a non polar bond?
An NH3 molecule, also known as an ammonia molecule is polar. The molecule's polarity and its ability to form hydrogen bonds, makes ammonia mix very well with water.
Is NH3 plar?
NH3 is the molecular formula for ammonia, and each N-H bond is polar, and the 3-D structure of the molecule makes the molecule polar. NH3 molecules will form hydrogen bonds with other molecules. Refer to the related links for an illustration of the ammonia molecule.
Is h2 polar or nonpolar molecule?
H2S is considered a polar molecule. Its construction allows it to have dipoles and dipole moments, which makes it polar.
Is IF5 polar or non polar?
IF5 is considered a type of polar molecule. It is a polar molecule because it can have dipole moments due to uneven charges.
Is ammonia polar non polar or ionic?
