Give systematic names for the following binary compounds: (a) BaS

Verified step by step guidance

1. Identify the elements in the compound: Ba (Barium) and S (Sulfur).
2. Determine the type of compound: BaS is a binary ionic compound.
3. Name the metal (cation) first: Barium.
4. Name the non-metal (anion) second, changing the ending to '-ide': Sulfur becomes sulfide.
5. Combine the names: The systematic name for BaS is Barium sulfide.

Key Concepts

Binary Compounds

Binary compounds consist of two different elements. In chemistry, these compounds can be ionic or covalent, depending on the nature of the bond formed between the elements. Understanding the type of binary compound is essential for determining the correct naming conventions.

Ionic Compounds

Ionic compounds are formed when electrons are transferred from one atom to another, resulting in the formation of charged ions. In the case of BaS, barium (Ba) donates electrons to sulfur (S), creating Ba²⁺ and S²⁻ ions. The systematic naming of ionic compounds involves naming the cation first followed by the anion.

Nomenclature Rules

Nomenclature rules provide a systematic way to name chemical compounds. For binary ionic compounds, the name of the metal (cation) is followed by the name of the non-metal (anion) with its ending changed to '-ide.' For BaS, the systematic name is barium sulfide, reflecting the elements involved and their ionic charges.
