Write the names for each of the following ions: b. Sr²⁺

Verified step by step guidance

1. Identify the element symbol 'Sr' from the periodic table.
2. Determine the name of the element corresponding to the symbol 'Sr'.
3. Recognize that 'Sr' stands for Strontium, which is an alkaline earth metal.
4. Understand that the superscript '²⁺' indicates a positive charge of 2, meaning it has lost two electrons.
5. Combine the element name with the word 'ion' to form the name 'Strontium ion'.

Key Concepts

Ionic Compounds

Ionic compounds are formed when atoms transfer electrons, resulting in the formation of charged ions. These compounds typically consist of a metal cation and a non-metal anion. Understanding ionic compounds is essential for naming ions, as it helps to identify the charge and the elements involved.

Cation and Anion

Cations are positively charged ions that result from the loss of electrons, while anions are negatively charged ions formed by the gain of electrons. In the case of Sr²⁺, strontium has lost two electrons, making it a cation. Recognizing the difference between these two types of ions is crucial for correctly naming them.

Nomenclature of Ions

The nomenclature of ions involves specific rules for naming cations and anions based on their elemental composition and charge. For example, cations derived from metals often retain the name of the element, while anions typically have names ending in '-ide' or '-ate' depending on their composition. Familiarity with these naming conventions is necessary to accurately identify and name ions.
