What is the reaction between sodium and iodine?
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na+) and iodide anions (I−) in a crystal lattice.
What bond will form between sodium Na and iodine I atoms?
ionic compounds
In ionic compounds, the atoms are present as ions; that is, as charged particles. For example, in NaI, the sodium is present as sodium ions and the iodine as iodide ions.
Is sodium iodide ionic?
Sodium iodide is a water-soluble ionic compound with a crystal lattice.

How is the atomic number of iodine determined?
The iodine atoms are added as anions, and each has a 1− charge and a mass number of 127. Determine the numbers of protons, neutrons, and electrons in one of these iodine anions. Solution The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus.
Which is an iodide salt and which is a sodium salt?
More… Sodium iodide is a metal iodide salt with a Na (+) counterion. It is an inorganic sodium salt and an iodide salt. Sodium iodide is a water -soluble ionic compound with a crystal lattice.
How is methyl iodide converted to molecular iodine?
Inhaled methyl iodide and molecular iodine (I2) are rapidly converted to iodide. /Methyl iodide and iodine/
How is sodium iodide used in veterinary medicine?
Sodium iodide is a water -soluble ionic compound with a crystal lattice. Sodium iodide is a source of iodine and can be administered as a supplement for total parenteral nutrition but is more commonly used in veterinary medicine. Radiolabelled compound, [DB09293], is used as a diagnostic tool to evaluate thyroid function and morphology.
