Guida verificata passo dopo passo1
Identify the ions present in the compound NaCl. Sodium (Na) is a metal and forms a cation with a charge of +1, written as Na\^{+}. Chlorine (Cl) is a nonmetal and forms an anion with a charge of -1, written as Cl\^{-}.
Recognize that NaCl is an ionic compound formed by the combination of the sodium cation and the chloride anion.
Recall the naming convention for ionic compounds: the cation (metal) name is written first, followed by the anion (nonmetal) name. For monatomic anions, the element name is modified to end with '-ide'.
Apply the naming rule: Sodium remains 'sodium' and chlorine becomes 'chloride' when naming the anion in an ionic compound.
Combine the names of the cation and anion to get the correct name of the compound: 'Sodium chloride'.
