Study Notes
Chemical Bonding Terms
-
Polyatomic Ion: A type of ion consisting of two or more atoms bonded together, acting as a single charged entity.
-
Ternary Ionic Compounds: Formed from three different elements, including at least one metal and one nonmetal.
Naming Ternary Ionic Compounds
-
Process of Naming: Similar to binary ionic compounds, the cation is named first followed by the anion.
-
Traditional Naming System:
- The cation retains its elemental name.
- The anion's name is derived from the elemental name by eliminating the ending and replacing it with "ide."
-
Stock System Naming:
- Begins with naming the cation followed by the anion.
- Cation maintains its elemental name, while the anion adopts an "ide" ending after removing the original ending.
Writing Ternary Ionic Compounds
-
Formula Construction:
- Write the cation's symbol and charge, then the anion's symbol and charge.
- Use the crisscross method to balance charges for a neutral compound.
Properties and Structures of Ionic Compounds
-
Ionic Compound Properties:
- Exhibit crystal lattice structures.
- Conduct electricity in liquid form.
- Have high melting and boiling points.
-
Ionic Crystal: Defined as a structured arrangement of ions within the compound.
-
Ionic Lattice: A repeating pattern of positively and negatively charged ions.
-
Crystal Lattice: A three-dimensional arrangement of particles in a solid state.
Electrolytes and Thermal Properties
-
Electrolyte: An ionic compound capable of conducting electricity when dissolved in liquid states.
-
Endothermic Reaction: A process that absorbs heat or energy from its surroundings.
-
Exothermic Reaction: A process that releases heat or energy.
Lattice Energy and Metal Properties
-
Lattice Energy: The energy emitted when one mole of a crystalline compound is formed from gaseous ions.
-
Metal Lattice: A structural arrangement of cations and electrons that determine a metal's malleability, ductility, and conductivity.
Metallic Bonding Concepts
-
Electron Sea Model: Describes a structure in metallic solids where valence electrons are pooled together, forming a sea of electrons.
-
Delocalized Electrons: Electrons that can freely move between atoms within metallic bonds.
-
Metallic Bond: Formed through the attraction of positively charged metal ions to the surrounding electron sea.
-
Metallic Bond Properties: Dependent on the number of delocalized electrons, the positive charge of the metal cations, and the ionic radius of the cations.
-
Alloy: A mixture of two or more metals, combining their properties for enhanced performance applications.
