Ionic Bond
|
Chemical bonding that results from the electrical attraction between large numbers of cations and anions. In a pure ionic bond, atoms give up electrons to other atoms (stealers).
|
|
|
Covalent Bonds
|
Covalent bonding results from the sharing of electron pairs between two atoms. In a purely covalent bond, the shared electrons are "owned" equally by the two bonded atoms.
|
|
|
Polar Bonds
|
Description of a bond that has uneven distribution of charge due to unequal sharing of bonding. (hoggers)
|
|
|
Non-Polar Bonds
|
A covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge. (sharers)
|
|
|
Octet Rule
|
Chemical compounds tend to form so that each atom, by gaining, losing, or sharing electrons, has an octet in its highest energy occupied energy level. Formed by covalent bond that fills s and p orbitals (8 electrons).
|
|
|
Lewis Dot Symbols
|
Symbols that represent valence electrons.
|
|
|
Caton
|
A positive ion
|
|
|
Anion
|
A negative ion
|
|
|
Diatomic Gases
|
Cl2, F2 H2, N2,and O2; these gases are made by the combination of two homogeneous elements.
|
|
|
Polyatomic Ions
|
A charged group of covalently bonded atoms.
|
|
|
Electronegativity
|
Measure of an atom's ability to attract electrons
|
|
|
Solute
|
The substance dissolved in a solution.
|
|
|
Solvent
|
The dissolving medium in a solution.
|
|
|
Solution
|
A homogeneous mixture of two or more substances in a single phase.
|
|
|
Intermolecular Attraction
|
Forces of attraction or repulsion which act between neighboring particles (atoms, molecules or ions). They are weak compared to the intramolecular forces.
|
|
|
Intramolecular Attraction
|
Any force that holds together the atoms making up a molecule or compound.They contain all types of chemical bond. They are stronger than intermolecular forces.
|
|
|
Melting Point
|
The temperature at which a solid becomes a liquid.
