|
The enthalpy change accompanying the breakage of a given bond in a mole of gaseous molecules.
|
Bond Energy
|
|
|
The distance between the nuclei of two bonded atoms.
|
Bond Length
|
|
|
The number of electrons pairs shared by two bonded atoms.
|
Bond Order
|
|
|
An electron pair shared by two nuclei; the mutual attraction between the nuclei and the electron pair forms a covalent bond.
|
Bonding Pair
|
|
|
The idealized bonding type that is based on localized electron-pair sharing between two atoms with little difference in their tendencies to lose or gain electrons(usually nonmetals).
|
Covalent Bonding
|
|
|
A covalent bond that consists of two bonding pairs; two atoms sharing four electrons in the form of one sigma and one pie bond.
|
Double Bond
|
|
|
The relative ability of a bonded atom to attract shared electrons.
|
Electronegativity
|
|
|
The difference in electronegativities between the atoms of a bond.
|
Electronegativity Difference
|
|
|
The hypothetical charge on an atom in a molecule or ion.
|
Formal Charge
|
|
|
The idealized bonding type based on the attraction of oppositely charged atoms with large differences in their tendencies to lose or gain electrons(usually between metals and nonmetals)
|
Ionic Bonding
|
|
|
A notation in which the element symbol represents the nucleus and inner elctrons, and surrounding dots represent the valence electrons.
|
Lewis electron-dot symbol
|
|
|
A structural formula consisting of electron-dot symbols, with lines as bonding pairs and dot pairs as lone pairs.
|
Lewis structure
|
|
|
An electron pair that is part of an atom's valence shell but not involved in covalent bonding.
|
Lone Pair
|
|
|
An idealized type of bonding based on the attraction between metal ions and their delocalized valence electrons.
|
Metallic Bonding
|
|
|
A covalent bond between identical atoms such that the bonding pair is shared equally.
|
Nonpolar Covalent Bond
|
|
|
The observation that when atoms bond, they often lose, gain, or share electrons to attain a filled outer shell of eight electrons.
|
Octet Rule
|
|
|
A covalent bond in which the electon pair is shared unequally, so the bond has partially negative and partially positive poles.
|
Polar Covalent Bond
|
|
|
One of two or more Lewis structures for a molecule that cannot be adequately describe by a single structure. These differ only in the position of electron pairs.
|
Resonance Structure
|
|
|
The weighted average of the resonance structures of a molecule.
|
Resonance Hybrid
|
|
|
A bond that consists of one electron pair.
|
Single Bond
|
|
|
A covalent bond that consists of three bonding pairs, two atoms sharing six electrons; one sigma and two pie bonds.
|
Triple Bond
|
