Sodium sulfide is a chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O.
To obtain a valence shell octet, sodium forms an ion with a 1+ charge, while the sulfur ion has a 2− charge. Two sodium 1+ ions are needed to balance the 2− charge on the sulfide ion. Rather than writing the formula as NaNaS, we shorten it by convention to Na 2 S.
Write the chemical formula for an ionic compound composed of each pair of ions. the sodium ion and the sulfur ion; the aluminum ion and the fluoride ion; the 3+ iron ion and the oxygen ion; Solution. To obtain a valence shell octet, sodium forms an ion with a 1+ charge, while the sulfur ion has a 2− charge.
A chemical formula is a concise list of the elements in a compound and the ratios of these elements. To better understand what a chemical formula means, we must consider how an ionic compound is constructed from its ions.
12 Ιουν 2014 · The formula for sodium sulfide is N a2S. Since this is an ionic compound, you must balance the charges so that overall charge of the compound is neutral. Sodium, an alkali metal, has a tendency to lose one electron. As a result sodium normally carries a positive one charge. Sulfur, a nonmetal, has a tendency to gain 2 electrons.
Chemical Compound Formulas. Sodium Sulfide. Sodium sulfide - Na 2 S. What is Sodium sulfide? Sodium sulfide is an inorganic chemical compound with the formula Na2S that has attained an important position in the organic chemical industry. It is a strong alkaline solution when exposed to moist air it smells like rotten eggs.
