Write the names for each of the following ions:a. Li⁺

Verified step by step guidance

1. Step 1: Identify the element symbol in the ion. In this case, the symbol is 'Li'.
2. Step 2: Determine the element name corresponding to the symbol 'Li'. This is lithium.
3. Step 3: Recognize that the ion has a positive charge, indicated by the superscript '+'.
4. Step 4: Understand that a positive charge means the ion is a cation, which is typically named by the element name itself.
5. Step 5: Conclude that the name of the ion 'Li⁺' is 'lithium ion'.

Key Concepts

Ions

Ions are charged particles that form when atoms gain or lose electrons. A positively charged ion, known as a cation, occurs when an atom loses one or more electrons, while a negatively charged ion, called an anion, forms when an atom gains electrons. Understanding the nature of ions is crucial for naming them correctly.

Monatomic Ions

Monatomic ions consist of a single atom with a positive or negative charge. For example, Li⁺ is a monatomic cation formed from lithium, which has lost one electron. Recognizing the difference between monatomic and polyatomic ions is essential for accurate nomenclature in chemistry.

Nomenclature of Ions

The nomenclature of ions involves specific rules for naming ions based on their charge and composition. Cations are typically named after the element, while anions often have their names modified to end in '-ide' for monatomic ions. Familiarity with these naming conventions is necessary for correctly identifying and writing the names of ions.
