The formula for sodium iodide is NaI. Its molar mass is 149.89 grams per mole. It is a white solid substance with a density of 3.67 grams per cubic centimeter. Its melting point is 1,222 degrees Fahrenheit, and its boiling point is 2,379 degrees Fahrenheit.
Sodium iodide has a solubility in water of 184 grams per 100 milliliters at 77 degrees Fahrenheit. It takes part in the Finkelstein reaction, in which an alkyl chloride is converted into an alkyl iodide. People who suffer from iodine deficiencies use sodium iodide as a food supplement. It is also an ingredient in iodized table salt.Learn More
The atoms involved in ionic bonding are held together by an electrostatic force of attraction between a positive and a negative ion. Ionic bonds are only formed between metals and non-metals.Full Answer >
Alkanes have no double or triple bonds, alkenes have one or more double bonds and alkynes have one or more triple bonds. Alkanes, alkenes and alkynes are all types of hydrocarbons.Full Answer >
An atom of boron has three valence electrons. The valence electrons of boron occupy the second orbit around the nucleus of the boron atom. Thus, the boron atom has an electronic configuration of [He] 2s2 2p1.Full Answer >
The element phosphorus has five valence electrons. Valence electrons refer to the amount of electrons in the outer shell of an atom. If an orbital is not full of atoms, it is likely to try to fill or deplete it in order to become more stable.Full Answer >
