Because around the quite small P atom (Five 3s2, 3p3 valence electrons in five new "s2p3"-hybrid orbitals in a trigonal bipyramidal shape) there is not enough space to be surrounded by five (5) quite big Iodine atoms (Seven 5s2, 5p5 valence electrons)
If phosphorus pentaiodide (PI5) has no lone pairs, it would adopt a trigonal bipyramidal shape. In this geometry, the phosphorus atom is at the center, with five iodine atoms positioned at the corners of the bipyramid, three in the equatorial plane and two in the axial positions. This arrangement allows for optimal spacing between the iodine atoms, minimizing repulsion.
Many possible genotypes, producing ,any possible phenotypes.
The reaction is not possible.
Yes, it is possible to have a population of 1.
It sure is possible.
The chemical formula for phosphorus pentiodide is PI5.
Theoretically PI5 should be formed as PCl5 but practically. due to large atomic size 5 iodine atoms can not attached directly with one phosphorus atom
The formula for phosphorus pentaiodide is PI5. It is a bright red solid with a molecular weight of 411.67 g/mol.
The compound PI5 is called phosphorus pentaiodide. It is a covalent compound composed of one phosphorus atom and five iodine atoms.
PI5, or Phosphatidylinositol 5-phosphate, remains relatively unknown primarily due to its low abundance in biological systems and the complexity of its metabolic pathways. Research has focused more on other phosphoinositides, like PI3 and PI4, which have clearer roles in cell signaling and membrane dynamics. Additionally, the methods for studying phospholipids have historically favored more prevalent species, leaving PI5 and its functions less explored. As interest in lipid signaling grows, more discoveries about PI5 may emerge, clarifying its biological roles.

Don't know P2I5. PI5 (phosphorus pentaiodide) is more likely but couldn't find anything on that. Maybe this is meant: P2I4 , diphosphorus tetraiodide synthesized from phosphorus triiodide 2 PI3 → P2I4 + I2
The imaginary compound nitrogen pentaiodide would be NI5 , it would not be an acid- there are no ionisable H atoms. (or a Lewis acid- it has no lone pair.) There is a real compound NI3, a very unstable substance a contact explosive. There is a reported PI5, but that is disputed.
