It has a lone pair.So it is trigonal pyramidal
in XeO3 ,Xe shows sp3 but shape is pyramidal because of the presence of a lone pair of electrons on the central xenon atom. This lone pair distorts the shape of the molecule making it pyramidal.
pyramidal
The one that can readily identified as a man made structure (rather than a mound of earth with has a superficial pyramidal shape) and with the archaeology providing evidence of its builder is the Step Pyramid of the 3rd dynasty Pharaoh Djoser at Saqqara (Egypt). It was completed c.2650B.C.
The pyramidal structure suggests that the higher the rank, the fewer employees work or operate at that rank and, conversely, the lower the rank, the more federal employees work at that particular rank.
The judicial system of Great Britain is pyramidal in organization.
pyramidal
Trigonal pyramidal (like NH3)
It has a lone pair.So pyramidal in shape.
pyramidal
Ammonia (NH3) is an example.
Ammonia has a lone pair.Its shape is trigonal pyramidal.
Since NH3 has an free electron pair, it would be considered polar.
The molecule of ammonia has a trigonal pyramidal shape with angles of 106,7 0.
It is pyramidal in shape.It has a lone pair.
CH4 has four even repulsive units.So its shape is tetrahedral.NH3 has 3 units including a lone pair.So its shape is pyramidal
NH3 has a geometry of a flattened tetrahedron. Each hydrogen atom has 107.8 degrees between them, and a distance of 101.7 pm.
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.
