Chemical Bonding Flashcards
Define electronegativity
Measure of the tendency of an atom to attract a bonding pair of electrons
Define intermolecular bond
Bond occurring between atoms with atoms
Define a covalent bond
Sharing of at least one pair of electrons by two atoms
Define non-polar covalent bonds
Equal sharing of electrons
Polar covalent bonds
Unequal sharing of electrons leading to a dipole forming(because of difference in electronegativity)
Define ionic bond
Transfer of electrons and results in electronegativity attraction
Define metallic bonding
Between a positive kernel and a sea of delocalised electrons
Why do giant structures have high boiling point
They have strong covalent bonds
What determines the boiling and melting points of solids
It’s the electrostatic forces of attraction between the cat ions and anions in the lattice structure
