A chemical formula that shows the arrangement of atoms in a molecule or a polyatomic ion; each dash between two atoms indicates a pair of shared electrons
Bond Dissociation Energy
The amount of energy required to break a covalent bond between atoms; this value is usually expressed in kJ per mol of substance
One of two or more equally valid dot structures for a molecule or polyatomic ion; the actual bonding is a hybrid, or micture, of the resonance structures
A term used to describe a substance that shows a relatively strong attraction to an external magnetic field; these substances have molecules containing one or more unpaired electrons
Nonpolar Covalent Bond
A bond formed when the atoms in a molecules are alike and the bonding electrons are shared equally
Polar Covalent Bond/ Polar Bond
A bond formed when two different atoms are joined by a covalent bond and the bonding electrons are unequally shared
Van Der Waals Forces
A term used to describe the weakest intermolecular attractions; these include the dispersion forces and dipole interactions
The weakest kind of intermolecular attraction; this attraction is thought to be cause by the motion of electrons
A weak intermolacular force resulting from the attraction of oppositely charged regions of polar molecules
A relatively strong itnermolecular force in which a hydrogen atom that is covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another electronegative atom in the same molecule or one nearby
