iGCSE Chemistry - Simple Covalent Bonds

Hello All!

So,  had Chemistry yesterday, and trying to now make sense of Simple Covalent Compounds.

There are 3 ways to represent Simple Covalent Compounds, and I’m going to show them to you using the example of Ammonia, NH₃

1.       The Dot-And-Cross Diagram Way:

2.       The Lines Diagram Way:

 

 

3.       The Outer Energy Level Way: 

Ammonia is made up of 3 Hydrogen atoms and 1 Nitrogen atom, joined in Covalent Bonds. Hydrogen has 1 electron in its highest energy level, so it needs 1 more to complete its outer shell. Nitrogen has 5 electrons in its highest energy level, so it needs 3 more to complete its outer shell. So, Nitrogen shares the only 3 electrons from the 3 Hydrogen atoms, and the Hydrogen atoms share 3 of the 5 Nitrogen outer shell electrons.

So, do you get it?

I do!....

I think...hmm...

Byee!
