At the university, this ammonia molecule and its structure are studied in a special course on the structure of matter. But this happens in special courses. And in our case, everything is simpler. So this is what the record of the ammonia molecule looks like.
In an ammonia molecule, all bonds are covalent and polar. In this molecule, All d valence bonds are in sp3 hybridization.
This is how it looks in space.
H: N: H
The angle between bonds with hydrogen is 107.8. The molecule has a pyramidal structure with an N atom at its vertex and a triangle with three hydrogen atoms at its base.
