Three Main Types of Bonding | Ionic, metallic, covalent |
Occurs when a metal will lose an electron to a nonmetal, results in a cation and an anion, held together by electrostatic attraction | Ionic Bonding |
What hold together the ion of a cation and anion | Electrostatic Attraction |
Characteristics of Ionic Compounds | Solid crystals, brittle, high melting points, high boiling points, water soluble, electrolytes |
Can conduct electricity when molten or dissolved in water | Electrolytes |
The charge of the cation must balance out the charge of the anion to determine the formula unit | Formation of an ionic compound |
Indicates the ratio of cation to anion in any ionic compound | Formula Unit |
Groups of atoms that are covalently bonded, but carry an overall net charge | Polyatomic Ions |
NO3^-1 | Nitrate |
CO3^-2 | Carbonate |
OH- | Hydroxide |
SO4^-2 | Sulfate |
PO4^-3 | Phosphate |
The energy released when one mole of an ionic crystalline compound is formed from gaseous ions | Lattice Energy |
Consists of positively charged metallic cations that donate electrons to the "sea" | Metallic Bonding(Electron Sea Model) |
Are shared by all atoms and can move throughout the structure | The "sea" of electrons |
Thermal conductivity, electrical conductivity, malleability, ductility | Properties of metals |
Matter, lower melting and boiling points | Properties of covalent compounds |
Occurs when atoms are bound together to form a discrete molecule, have lower melting points and are nonconducters | Molecular Covalent Bonding |
Occurs when atoms are bound to multiple atoms to form a complex structure | Network Covalent Bonding |
The distance between two bonded atoms at the minimum potential energy | Bond Length |
The energy required to break a chemical bond | Bond Energy |
Occurs when there is more than one valid Lewis Structure | Resonance |
Compounds with the same molecular formula but different structural formulas | Isomers |
