Bonding Flashcards
Intramolecular Bond
A bond between atoms within a molecule
Valence Electrons
The electrons in the outermost energy level of an atom
Valency
The number of electrons gained,shared of lost to complete the outermost energy level
Covalent Bond
A sharing of at least one pair of electrons by two non metal atoms
Pure Covalent Bond
Covalent Bond in which the electron pair is shared equally
Electronegativity
The measure of the tendency of an atom to attract a bonding pair of electrons
Lone Pairs
These are electron pairs in the outermost energy level of an atom that do not take part in the chemical bonding process
Dative Covalent Compound
The Lone pair of an atom is shared with another atom which has an empty orbital in its outermost energy level
Bond Energy
The amount of energy required to break a specific bond.This is measured in kJ.mol
Bond Length
The distance between the nuclei of two covalent users bonded atoms (double and triple bonds are shorter than single bonds )
Ionic Bond
Transfer of electrons and subsequent electrostatic attraction
Metallic Bond
A bond between a positive kernel and a sea of delocalized electrons
Molecular Geometric
Refers to the three dimensional arrangement of the atoms within a molecule
Intermolecular Force
a weak force of attraction between molecules, ions, or atoms of noble gases
