According to two Wikipedia articles, phosphorus and iodine can form phosphorus triiodide (PI3) and diphosphorus tetraiodide (P2I4). These compounds are made from the covalent bonding between the phosphorus and iodine atoms. Nonmetals tend to form covalent bonds with other nonmetals.
Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
Chlorine
Polar bond between H and I in HI
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
This element is iodine because it is a halogen.
Phosphorus triodide is a chemical compound. It is made up of 1 phosphorus and 3 iodine atoms. It has the formula PI3 .

Carbon, phosphorus, sulfur, selenium, and iodine
Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
Iodine is added to a solution of white phosphorus in carbon disulfide as solvent to form phosphorus triiodide. P4 + 6I2 → 4PI3

Phosphorus is not a halogen. Only the elements of group 7 are halogens (fluorine, chlorine, bromine, iodine, and astatine).
