Ch. 7 Flashcards
Cation
A positively charged ion
Chemical Bond
The force that holds two atoms together
Anion
A negatively charged ion
Ionic Bond
The electrostatic force that holds oppositely charged particles together in an ionic compound
Ionic Compounds
Compounds that contain ionic bonds
Crystal Lattice
A three-dimensional geometric arrangement of particles
Electrolyte
An ionic compound whose aqueous solution conducts an electric current
Lattice Energy
The energy required to separate 1 molecule of the ions of an ionic compound
Formula Unit
The chemical formula for an ionic compound that represents the simplest ratio of the ions involved
Monatomic Ion
A one-atom ion
Polyatomic Ion
An ion made up of more than one atom
Oxyanion
A polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atoms
Electron Sea Model
All the metal atoms in a metallic solid contribute their valence electrons to form a “sea” of electrons
Delocalized Electrons
The electrons present in the outer energy levels of the bonding metallic atoms that are not held by any specific atom and can move freely from one atom to the next
Metallic Bond
The attraction of a metallic cation for delocalized electrons
