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

Verified step by step guidance

1. Identify the element symbol 'Sr' on the periodic table.
2. Determine the name of the element corresponding to the symbol 'Sr'.
3. Recognize that 'Sr' stands for Strontium.
4. Understand that the superscript '2+' indicates a positive charge of 2, meaning it is a cation.
5. Combine the element name with the word 'ion' to name the cation as 'Strontium ion'.

Key Concepts

Ionic Charge

Ionic charge refers to the electrical charge that an ion carries, which results from the loss or gain of electrons. In the case of Sr²⁺, the '²⁺' indicates that the strontium ion has lost two electrons, giving it a positive charge. Understanding ionic charge is essential for naming ions and predicting their behavior in chemical reactions.

Cation

A cation is a positively charged ion formed when an atom loses one or more electrons. Strontium (Sr) typically forms a cation with a charge of +2, represented as Sr²⁺. Recognizing the difference between cations and anions (negatively charged ions) is crucial for understanding ionic compounds and their properties.

Element Naming Conventions

Element naming conventions involve the systematic way in which ions and elements are named based on their chemical properties and structure. For example, the name for Sr²⁺ is 'strontium ion,' which reflects its elemental name 'strontium' along with its ionic charge. Familiarity with these conventions is important for accurately communicating chemical information.
