Electron dot structure of nh3 class 10

In this topic, we will discuss the electron dot structure of `NH_3` under the following points or steps.

In the series of electron dot structures, we are discussing electron dot structures of different compounds.

   1.   Formula of ammonia

   2.   Electronic configuration of nitrogen

   3.   Electronic configuration of hydrogen

   4.   Find the central atom in the compound

   5.   Draw the structural formula of Ammonia

   6. Electron dot structure of Ammonia

6.    

Formula of ammonia

`NH_3`

Electronic configuration of nitrogen

The atomic number of Nitrogen is 7

`1s^2 2s^2 2p^3`

Nitrogen has 5 valence electrons in the outermost shell and it requires 3 electrons to complete its Octet.

Electronic configuration of hydrogen

`1s^1`

Hydrogen has 1 valence electron in the outermost shell (only one shell) and requires one electron to complete an octet (stable electronic configuration).

Three hydrogen atoms are present in ammonia.

Find the central atom in the compound

One Nitrogen atom combines with three hydrogen atoms, so Nitrogen is the central atom in ammonia.

 

 Structural formula of ammonia

Now we have found that Nitrogen is the central atom of ammonia.

Nitrogen shares three electrons with three hydrogen atoms forming a single bond between them.

 

Electron dot structure of `NH_3`

Nitrogen has one lone pair of electrons (unshared electrons).

So, this is the electron dot structure of ammonia class 10 which is very useful for students of class 10 onwards.
