Name the following ionic compounds: (a) KCN (b) NaBrO₂ (c) Sr(OH)₂ (d) CoTe

Guida verificata passo dopo passo

Identify the cation and the anion in the compound. Here, the cation is Na (sodium) and the anion is BrO2.

Recognize that Na is a Group 1 element, which means it forms a +1 charge as a cation, Na⁺.

Determine the anion BrO2. This is a polyatomic ion known as bromite, which typically carries a -1 charge.

Combine the names of the cation and the anion. The cation name (sodium) comes first, followed by the anion name (bromite).

The name of the compound is 'sodium bromite'.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Ionic Compounds

Ionic compounds are formed when atoms transfer electrons, resulting in the formation of positively charged cations and negatively charged anions. These oppositely charged ions attract each other, creating a stable compound. Understanding the structure and properties of ionic compounds is essential for naming them correctly.

Polyatomic Ions

Polyatomic ions are ions composed of two or more atoms covalently bonded together, which carry a net charge. In the case of NaBrO2, the bromite ion (BrO2-) is a polyatomic ion that must be identified correctly to name the compound. Familiarity with common polyatomic ions is crucial for proper nomenclature.
