Final answer:
The compounds are named as follows:
KN₃ is potassium nitride.
B₄C₃ is boron carbide.
SiS₂ is silicon disulfide.
Step-by-step explanation:
Chemical nomenclature involves systematically naming chemical compounds based on their composition and structure. In the given compounds:
KN₃ consists of potassium (K) and nitrogen (N) ions. The compound is named potassium nitride, where the metal name (potassium) is followed by the non-metal root with an -ide suffix (nitrogen).
B₄C₃ is composed of boron (B) and carbon (C) atoms. The compound is named boron carbide, where the metalloid (boron) is followed by the non-metal root with an -ide suffix (carbon).
SiS₂ contains silicon (Si) and sulfur (S) atoms. The compound is named silicon disulfide, where the metalloid (silicon) is followed by the non-metal root with an -ide suffix (sulfur).
These systematic names adhere to the conventions of chemical nomenclature, ensuring clarity and consistency in communication among scientists. The naming conventions help convey the composition and identity of compounds, allowing for precise communication in the field of chemistry. Understanding these names is fundamental in chemistry, enabling researchers to convey information about compounds and facilitating effective communication in scientific literature and discussions.
