Chemistry - Structure and Bonding - Definitions Flashcards
Covalent Bond
A bond formed by a shared paired of electrons.
Ionic Bond
The electrostatic attraction between oppositely charged ions.
Metallic Bond
The electrostatic attraction between positive meta ions and delocalised electrons.
Coordinate Bond
A shared pair of electrons which has been provided by one of the bonding atoms only.
Electronegativity
A measure of the attraction of a bonded atom for the pair of electrons in a covalent bond.
Van Der Waals Forces
Very weak attractive forces between induced dipoles in neighbouring molecules.w
Dipole- Dipole Interactions (permanent dipole)
An attractive force between permanent dipoles in neighbouring polar molecules.
Hydrogen Bonding
A strong dipole- dipole attraction between an electron-deficient hydrogen atom on one molecule and a lone pair of electrons
