I2 symbol chemistry. Iodine exhibits some metallic-like properties. Iodine is a bluish-black, lustrous solid. Related Topics. In aqueous solution, chlorine could oxidize iodine to iodic acid; in alkaline solutions, excess chlorine could oxidize iodine to periodic acid. The periodic table is a chart that shows how chemical elements are related to each other. The formula is written using the symbols for the elements and subscripts to indicate the number of atoms present. 904.

Feb 7, 2019 · The list of 118 Elements and their symbols and atomic numbers will prove useful to beginners in chemistry. Iodine's chemical properties are similar to the lighter halogens above it, fluorine, chlorine, and bromine. The chemical formula for iodine is I2, which indicates that it is composed of two iodine atoms. It forms compounds with most elements, but is less reactive than the other halogens, which displace it from iodides. For simplicity, we’ve deliberately omitted their Latin names. Aug 9, 2025 · Iodine, chemical element, a member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. Iodine Formula: I 2 Molecular weight: 253. It is a steel-gray solid that changes into beautiful purple vapors when heated. But its physical appearance is very different. It volatilises at ambient temperatures into a pretty blue-violet gas with an irritating odour. In this chapter, we will learn the meaning of the symbols used in chemistry to represent elements and compounds, and the information these symbols convey microscopically and macroscopically. Chemical symbol The periodic table, elements being denoted by their symbols Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities.

Apr 29, 2025 · (1) I2+H2S=S+2HI (2) I2+2S2O32-＝S4O62-+2I- The latter reaction can be used to quantify iodine in analytical chemistry, which is the basis of the iodometric method. com Element Iodine (I), Group 17, Atomic Number 53, p-block, Mass 126. Elemental iodine hence forms diatomic molecules with chemical formula I 2, where two iodine atoms share a pair of electrons in order to each achieve a stable octet for themselves; at high temperatures, these diatomic molecules reversibly dissociate a pair of iodine atoms.
