what is the name for Nal
The correct answer and explanation is:
Correct Answer: Sodium iodide
Explanation:
NaI stands for sodium iodide, which is an ionic compound composed of two elements: sodium (Na) and iodine (I). The name follows standard naming conventions in inorganic chemistry where the name of the metal (sodium) comes first, followed by the name of the non-metal (iodine) with its ending changed to “-ide.” Thus, iodine becomes iodide, resulting in the name “sodium iodide.”
Sodium iodide forms when sodium, a group 1 alkali metal, loses one electron to become a positively charged sodium ion (Na⁺), and iodine, a group 17 halogen, gains one electron to become a negatively charged iodide ion (I⁻). The electrostatic attraction between these oppositely charged ions forms the ionic bond that holds the compound together.
Sodium iodide is a white, crystalline solid that is highly soluble in water. It is commonly used in medicine, especially as a source of iodine in the treatment and prevention of iodine deficiency. It is also used in radiation detection equipment because of its ability to scintillate, or emit light, when exposed to radiation.
One notable use of sodium iodide is in radioactive form, specifically sodium iodide-131 (NaI-131), which is used in nuclear medicine for imaging and treatment of thyroid diseases such as hyperthyroidism and thyroid cancer. Iodine is selectively taken up by the thyroid gland, making iodide compounds especially useful in diagnosing and treating thyroid-related conditions.
In summary, the compound NaI is called sodium iodide. It consists of a metal and a halogen bonded ionically and has important applications in medicine, nutrition, and scientific instrumentation.
