Solution
1
Explain ionic bonding: Ionic bonding occurs between metals and non-metals. Metals lose electrons to form cations, while non-metals gain electrons to form anions. The electrostatic attraction between the oppositely charged ions forms the ionic bond. The compound formed is electrically neutral
2
Rules for writing ionic formulas:
- Write the symbol of the cation followed by the anion.
- Balance the charges to ensure the compound is neutral.
- Use parentheses when a polyatomic ion needs more than one unit to balance the charge.
Example:
3
Rules for naming ionic compounds:
- Name the cation first, followed by the anion.
- For transition metals, use Roman numerals to indicate the charge.
Example: is named iron(III) chloride
4
Rules for drawing Lewis structures:
- For atoms: Represent valence electrons as dots around the element symbol.
- For ionic compounds: Show the transfer of electrons from the metal to the non-metal, resulting in cations and anions.
Example:
Answer
The key concepts of ionic bonding include the types of elements involved, the rules for writing formulas and naming compounds, and the method for drawing Lewis structures.
Key Concept
Ionic bonding involves the transfer of electrons between metals and non-metals, resulting in the formation of cations and anions.
Explanation
Ionic compounds are electrically neutral, and their formulas and names follow specific rules to reflect the charges and composition of the ions involved. Lewis structures visually represent the transfer of electrons and the resulting ions.
