Lead (II) iodide
Transition metals always need roman numerals to represent their charges.
PbI4Lead iodide========
The chemical formula is PbI4.Pb(4+) + 4 I-
The chemical name of PbI4 is lead (IV) iodide.
Lead iodide is a chemical compound with the formula PbI2. It is a yellowish solid that is used in various applications, including in the manufacture of solar cells and in X-ray detection devices. Lead iodide can also be toxic if ingested or inhaled.
PbI does not exist. There are, however PbI2 and PbI4. Neither are good electrolytes.
PbI4Lead iodide========
PbI4 does not exist because lead (Pb) typically has a +2 oxidation state in its compounds, forming stable compounds like PbI2. In PbI4, lead would need to assume a +4 oxidation state; however, this state is less stable due to the inert pair effect, where the s-electrons of lead are less likely to participate in bonding. Additionally, the larger iodine atoms create steric hindrance that destabilizes a +4 lead compound. As a result, PbI4 is not a viable compound under normal conditions.
The compound PbI4 is lead (II) iodide, where the lead ion has a charge of +2 and the iodide ion has a charge of -1.
Lead (II) iodide, which has PbI2 as its chemical formula, exists only this way and not in the form PbI4 as someone might guess. Though lead has a +2 and a +4 for its oxidation states, iodine is too weak an oxidizer to form the second lead-iodine compound. This stuff is toxic because of the lead, and you can read more about it by using the supplied link to the Wikipedia article.
The chemical formula is PbI4.Pb(4+) + 4 I-
The chemical name of PbI4 is lead (IV) iodide.
Lead (II) iodide is PbI2. Lead (IV) iodide is PbI4.
PbBr4 and PbI4 are unstable due to the high oxidation state of lead (Pb) in these compounds, which makes them prone to reduction. Lead typically exhibits stable oxidation states of +2 and +4, but in these tetrahalides, the +4 state is less stable due to the larger size and lower electronegativity of bromine and iodine, which can lead to bond weakening. Additionally, the formation of stable lower oxidation state compounds, such as PbBr2 or PbI2, is thermodynamically favored, contributing to the instability of PbBr4 and PbI4.
Lead iodide is a chemical compound with the formula PbI2. It is a yellowish solid that is used in various applications, including in the manufacture of solar cells and in X-ray detection devices. Lead iodide can also be toxic if ingested or inhaled.
It is very slightly soluble in water.In a saturated solution:[Pb2+] = 1.2x10-2 mol/L[Br-] = 2.4x10-2 mol/Lbecause [Pb2+]*[Br-]2 = Ks = 6.3*10-6 and [Br-] = 2*[Pb2+]
It is a compound.
Lead(IV) iodide, or PbI4 is unknown and not present, because Iodine is not that much strong oxidizer to oxidize Lead or Lead(II) ions to Lead(IV) ions. However, Oxygen and Fluorine have this oxidizing power, and thus forming compounds of Lead(IV).
