Web6 apr. 2024 · It occurs abundantly in nature in compounds, especially common salt —sodium chloride (NaCl)—which forms the mineral halite and constitutes about 80 percent of the dissolved constituents of seawater. Properties and production Sir Humphry Davy Because sodium is extremely reactive, it never occurs in the free state in Earth’s crust. WebComparison of melting points of ionic compounds is generally done by considering the following two factors: 1. Charge of the cation/anion : More the charge of cation or anion, … براون bt3010
