From what I can remember it was 1 atom at the the top with three atoms adjacent at the base. ( Hope that makes sense)

Trigonal pyramidal refers to a molecular geometry in which there are three atoms bonded to a central atom, creating a pyramid-like shape with a bond angle of around 107 degrees. This geometry is commonly found in molecules with a central atom surrounded by three bonding pairs and one lone pair of electrons. Examples of molecules with a trigonal pyramidal shape include ammonia (NH3) and phosphine (PH3).
CH2NH2 is trigonal pyramidal. It has a central nitrogen atom with three bonded atoms and one lone pair, resulting in a trigonal pyramidal geometry.
No it is pyramidal in shape.Electronic geometry is tetrahedral
Trigonal pyramidal. Think of the phosphorus as being at the peak of a pyramid and the three chlorides forming the three corners of the pyramis base.
The electron geometry of NCl3 is trigonal pyramidal (four electron groups around the central nitrogen atom). The molecular geometry of NCl3 is also trigonal pyramidal, as the three chlorine atoms and lone pair of electrons repel each other to form this shape.
No, CH2O (formaldehyde) is a trigonal planar molecule with the carbon atom at the center of the triangle formed by the three atoms. It is not pyramidal in shape.
