Term
Lattice energy- ion size
Definition
Bigger ions have less lattice energy. Attraction between cations and anions decreases.
Term
Lattice energy- ionic charge
Definition
Increase in charge increases lattice energy.
Term
Single bonds
Definition
Weak and long.
Term
Multiple bonds
Definition
Strong and short.
Term
Isomer
Definition
Same molecule/ion, different structure.
Term
Free Radicals and What Neutralizes them
Definition
Molecules and ions that have an odd number of electrons. Antioxidants neutralize them.
Term
VSEPR
Definition
Valence Shell Electron Pair Repulsion Theory
Term
Ionic bond
Definition
Metal with nonmetal. Transfer
Term
Covalent bond
Definition
Nonmetal with nonmetal. Share
Term
Metallic bond
Definition
Metal with metal. Pooling
Term
Ionic properties
Definition
Hard, rigid, brittle. Ions held in specific positions in a crystal. Good solubility, high melting point, poor conductor as solid.
Term
Covalent properties
Definition
Atoms overlap orbitals so electrons exist in both. Represented by lines in structures. Unshared electrons are called unshared or lone pairs. Shared by bonds. Strength depends on situation
Term
Metallic properties
Definition
Good conductors, strong, malleable, ductile, and luster
Term
