The key difference between iodine and iodide is that the iodine is a chemical element whereas the iodide is an anion. The terms iodine and iodide sound similar, but we cannot use them interchangeably because they are two different chemical species.

The below infographic provides more facts about the difference between iodine and iodide. Moreover, there are few other differences such as the number of electrons in each chemical species, the reactivity, etc. This is because iodine is different from iodide. Therefore, most of the times, we use these two terms interchangeably, which is wrong. Iodine and iodide are closely related terms because iodide is derived from iodine. What is the Difference Between Iodine and Iodide? Also, due to the same reason, iodide is less hydrophilic than other small anions. Moreover, iodide forms comparatively weak bonds with opposite ions due to the same reason of being a large ion. Above all, iodide is the largest monatomic anion because it forms from the iodine atom that has comparatively a large atomic size. We name the chemical compounds consisting of this anion commonly as “iodides”. Accordingly, the chemical symbol of iodide is I – , and the molar mass of this ion is 126.9 g/mol. This anion forms when iodine atom obtains an electron from outside. However, it is the weakest oxidizing agent among other halogens due to its large atomic size.

Electron configuration – 4d 10 5s 2 5p 5Ībove all, iodine is a strong oxidizer this is mainly because it has an incomplete octet of electron configuration in which it lacks one electron to fill up the outermost p orbital.

Appearance – lustrous, metallic-grey solid.

Some chemical facts about iodine are as follows: However, the -1 oxidation is the most common among them, which results in the iodide anion. Moreover, there are many oxidation states that iodine can exist. Furthermore, this compound readily undergoes sublimation to form the violet gas of iodine.

It has a lustrous, metallic-grey appearance. Also, this element exists in a solid state at room temperature. It is the heaviest halogen (halogens are group 17 chemical elements in the periodic table).

Iodine is a chemical element having the atomic number 53 and chemical symbol I. Side by Side Comparison – Iodine vs Iodide in Tabular Form Hence, iodine is an element with high atomic number 53, and we can represent it by the symbol I whereas iodide being an ion and is represented by 1.

#IODINE CHARGE DERIVED BY EACH ELEMENT FREE#

Iodine is a chemical compound that is purple in colour whereas iodide is an ion and cannot remain in free state implying it has to combine with another element or elements to form a compound. But, there are many who confuse with the two terms and use the two words interchangeably, which is not correct. We can understand the iodine and iodide variation very easily if one has a basic understanding of chemistry.
