Module 2, Topic 4 - Bonding & Structure Flashcards
Define “ionic bonding”
The electrostatic attraction between positive and negative ions
Define “covalent bonding”
The strong electrostatic attraction between a shared pair of electrons and nuclei of the bonded atoms
What is meant by a “dative” covalent bond?
Where 1 atom contributes both electrons needed for the bond to form
Define “electronegativity”
The ability of an atom to attract a pair of electrons in a covalent bond
Define “London forces”
The weakest intermolecular forces. They form between non-polar (molecules with different types of atoms) molecules as electrons become attracted to each other.
What is meant by “permanent dipole - dipole attraction”?
Forms between 2 polar covalent molecules. Forces of attraction between opposite charges on neighboring molecules.
What is meant by “hydrogen bonding”?
