Trigonal Pyramidal
Phosphine, or PH3, has (quite obviously) three hydrogen atoms singly bonded to a phosphorus atom. Because of the presence of a lone pair of electrons, the phosphorus atom is sp3 hybridized, and the electron orbitals adopt a tetrahedral configuration. As mentioned earlier, one orbital is non-bonding and thus the molecular shape is trigonal pyramidal.

PH3 is a molecular compound. It is made up of covalent bonds between phosphorus and hydrogen atoms, rather than ionic bonds between a metal and a nonmetal.
PCL5: Trigonal bipyramidal shape PH3: Trigonal pyramidal shape OF2: Bent shape ClO4-: Tetrahedral shape
A PH3 molecule has a triangular pyramidal shape. The central atom is the Phosphorus atom, which is connected to three Hydrogen atoms.
BeCl2
PH3 has a higher vapor pressure than NH3 due to the larger size and greater molecular weight of phosphorus compared to nitrogen. This results in weaker van der Waals forces between PH3 molecules, allowing them to escape and become a gas more easily than NH3 molecules.
The molecular shape of SCl6 is octahedral.
The molecular shape for CHI3 is trigonal bipyramidal.
Nitrogen is a diatomic molecule with a linear shape, as it consists of two nitrogen atoms bonded together.
