Chemical Bonding Flashcards
Intramolecular Bond
A bond which occurs between atoms within molecules.
Valence electrons
The electrons found in the outermost(highest) energy level of an atom.
Valency
The number of electrons gained, lost or shared to complete the outermost energy level.
Covalent bond
The sharing of at least one pair of electrons by two non-metal atoms.
Non-polar covalent(pure covalent)
An equal sharing of electrons.
Polar covalent
An unequal sharing of electrons leading to a dipole forming.
Electronegativity
A measure of the tendency of an atom to attract a bonding pair of electrons.
Ionic bond
A transfer of electrons and subsequent electrostatic attraction.
Metallic bonding
The bond between a positive kernel and a sea of delocalised electrons.
Bond Energy
The amount of energy needed to break a specific bond.
