WebThe bismuth tri-iodide ( B i I 3 ) is an inorganic compound. It is the result of the response of bismuth and iodine, which has inspired enthusiasm for subjective inorganic investigation. The topological indices are the numerical invariants of the molecular graph that portray its topology and are normally graph invariants. In 1975, Randic presented, in a bond-added … WebBismuth is normally found in an oxidation state of +3. In this state, the atom reacts with halogens to form trihalides. These halogens include fluorine, chlorine, bromine, and iodine, which form BiF 3, BiCl 3, BiBr 3, and BiI 3. With the exception of BiF 3, these compounds hydrolyze in water.
