The lewis structure of ammonia is the structure C.

Given:

The molecule ammonia NH_3

To find:

The correct Lewis structure of ammonia.

Solution:

Number of the nitrogen atoms in ammonia = 1

Number of the hydrogen atoms in ammonia = 3

The valence electrons in nitrogen atom = 5

The valence electrons in hydrogen atom = 1

Total valence electrons in ammonia molecule:

The total valence electrons = 8

Now draw the skeletal structure of ammonia and distribute the 8 valence electrons in such a way so that octet of each atom is complete as shown in the image attached.

So, the lewis structure of ammonia is the structure C.

Explanation:

Figure C is the correct Lewis dot structure of Ammonia.

alfred von schlieffen, german army chief of staff, was given instructions to devise a strategy that would be able to counter a joint attack. in december, 1905, he began circulating what later became known as the schlieffen plan. schlieffen argued that if war took place it was vital that france was speedily defeated.

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
