Respuesta :
To name compounds, usually, they are a combination of a metal and a nonmetal, between nonmetals and between metals. The two elements here are ammonium (NH₄) and sulfur (S). These are both nonmetals. When you name the compound, start by ammonium, followed by sulfur plus a suffix of -ide. The compound is ammonium sulfide.
Answer: The name of the given compound is ammonium sulfide.
Explanation:
We are given a chemical compound having chemical formula of [tex](NH_4)_2S[/tex]. This is formed by the combination of ammonium [tex](NH_4^+)[/tex] ions and sulfur [tex]S^{2-}[/tex] ions.
The given compound is an ionic compound because complete transfer of electrons takes place from one atom to another atom.
The nomenclature of ionic compounds is given by:
- Positive ion is written first.
- The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
- In case of transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.
Hence, the name of the given compound is ammonium sulfide.
