How do I determine the hybridization and bonding in ammonia?
Here's how to do it.
You draw the Lewis structure (Step 1) and use VSEPR theory to determine its electron domain geometry as tetrahedral and its molecular shape (Step 2) as a trigonal pyramid.
Then you consult a table like the one below.

You find that the
That shows that the
However, the molecular orbitals include both the
In the diagram above, the bond-line drawing shows that the
