IMF and Bonds Flashcards
Electronegativity
A measure of the tendency of an atom to attract a bonding pair of electrons.
Intramolecular bond
A bond which occurs between atoms within molecules.
Ionic bond
Transfer of electrons and subsequent electrostatic attraction.
Covalent
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 bonds
Unequal sharing of electrons leading to a dipole forming. This is the result of a difference in electronegativity between the atoms.
Metallic bond
The bond between a positive kernel and a sea of delocalised electrons.
Intermolecular force
A weak force of attraction between molecules, ions, or atoms of noble gases.
How are london forces formed
As the hydrogen molecules approach each other (get close)
• there is a dispersion of the electrons in each hydrogen molecule
• resulting in induced dipoles forming
• which are then able to attract each other
