Question

what is covalent bond? how ammonia formed ../

 

Answer 1

A covalent bond is a bond where the two elements being bonded SHARE electrons that make the bond.  So, if the bond is made by a sharing of electrons, then it is considered a covalent bond.

 

Ammonia has the formula of NH₃.  It can be formed many ways, but commercially it is formed by something called the Haber process.  This combines hydrogen gas (H₂) and nitrogen gas (N₂) in the ratio of of 3:1.  It looks like this:

3H₂ + N₂ ==> 2NH₃
