What are ionic compounds and how do you write ionic compounds?
Understand the Problem
The question is asking about the definition of ionic compounds and the rules or methods for writing their chemical formulas. This involves understanding the components of ionic compounds, such as cations and anions, and how to combine them correctly.
Answer
Ionic compounds consist of cations and anions; write with cation first, then anion, balancing charges.
Ionic compounds are neutral compounds formed from positively charged ions (cations) and negatively charged ions (anions). For binary ionic compounds, the formula is written by placing the cation's element symbol first, followed by the anion's element symbol, balancing the charges to ensure neutrality.

For binary ionic compounds, the formula is written by placing the cation's element symbol first, followed by the anion's element symbol, balancing the charges to ensure neutrality.
More Information
Ionic compounds are prevalent in both nature and technology, encountered in pharmaceuticals, batteries, and table salt. Each ionic compound's structure relies on the loss or gain of electrons to stabilize elements.
Tips
Mistaking the charge balance is a frequent error; remember the total charge must always be neutral. Another common error is writing the anion before the cation.
