A triangular based pyramid has 4 faces, 6 edges and 4 vertices
Trigonal Pyramidal. It is not trigonal planar because there is one lone pair around the central atom, just like the shape of ammonia.
The shape of NF3 is trigonal pyramidal because Flourine bonds to nitrogen three times leaving nitrogen with a left over bond pair of electrons.
It is pyramidal in shape.It has a lone pair.
Trigonal pyramidal
That would be Trigonal Pyramidal in shape and have an sp3 hybridization.
The phosphorus trichloride (PCl3) has a molecule with a trigonal pyramidal form.
It has a lone pair.So it is trigonal pyramidal
Trigonal Pyramidal. It is not trigonal planar because there is one lone pair around the central atom, just like the shape of ammonia.
There is a lone pair.It repels bond and shape become trigonal pyramidal.
Sulfur trifluoride is the trigonal pyramidal due to repulsion of lone pairs.
Trigonal pyramidal (like NH3)
Phosphorus trichloride has a trigonal pyramidal shape.
At first glance, you may assume the NH2- ion takes the form of a tetrahedral shape similar to CH4 or ammonia; however, there are two lone electron pairs. Therefore, like the shape of water (H2O), the shape can be called angular or V-shaped.
Ammonia has a lone pair.Its shape is trigonal pyramidal.
Trigonal pyramidal
It is Triangular pyramid It would be a trigonal pyramidal.
