Ammonia is a polar molecule. The hydrogen atoms are slightly more positive than the slightly negative nitrogen atom. The nitrogen has two electrons, which are not bonded to any other atoms. These are called lone pairs. The lone pairs indicate that ammonia's structure is not symmetrical, and the electrons are not evenly distributed.The electronegativity of the atoms involved in ammonia show that the bonds between N and H are moderately covalent.
3.3 - 2.2 = 0.8
Allie, you did a great job with the polarity. You explained very well that your molecule is polar. I liked the use of explain that hydrogen atoms are slightly more positive.
ReplyDeleteYou described and explained the polarity of the molecule very well and the diagram is a great asset to the explanation. The description is very accurate and thorough.
