Basic Bonding Flashcards
Covalent Bond?
A sharing of at least one pair of electrons by two non-metal atoms.
Non-polar (pure) covalent bond?
An equal sharing of at least one pair of electrons between two non-metal atoms.
Polar Covalent?
An unequal sharing of electrons leading to a dipole forming.
Ionic Bond?
A transfer of electrons and subsequent electrostatic attraction.
Metallic Bonding?
Bonding between positive kernels and a sea of delocalized electrons.
Electronegativity?
A measure of the tendency of an atom to attract a boding pair of electrons.
Ionization?
The reaction of a molecular substance with water to produce ions.
Dissociation?
The splitting of an ionic compound into its ions.
Neutralization (equivalence point).
The point where an acid and base have reacted so neither is in excess.
Salt?
A substance in which the hydrogen of an acid has been replaced by a cation.
Redox Reaction?
A reaction involving the transfer of electrons.
Intramolecular Bond?
A bond that exists between atoms within molecules.
Intermolecular Foce?
A force of attraction that exists between ions, molecules, and the atoms of noble gasses.
Why does the strength of London forces increase as the size of the molecule increases?
Larger molecules have more electrons which results in a greater electron density and a greater interactive surface. This results in stronger temporary dipoles that last longer.
