Properties of Compounds

These flashcards cover the fundamental properties of covalent and ionic compounds, including their conductivity, melting points, and the concepts of expanded octets and resonance structures.

Covalent Compounds

Compounds with relatively low melting points, sometimes soluble in water, not conductive when dissolved in water, and with weaker bonds that do not form charges.

Ionic Compounds

Compounds with relatively high melting points, soluble in water, conductive when dissolved in water, and with stronger bonds that form charges.

Expanded Octets

The ability of certain elements, particularly in the third row and below, to expand their octet and accommodate more than 8 electrons.

Resonance Structures

Different Lewis structures that can represent the same molecule, indicating that certain electrons can be delocalized across multiple bonds.

Conductivity in Solutions

A property of ionic compounds where they can conduct electricity when dissolved in water due to the presence of free-moving charged particles.

Melting Points

A physical property of compounds that can vary greatly, being lower in covalent compounds and higher in ionic compounds.
