Flashcards in Bonding and Structure Deck (10):
define ionic bonding
electrostatic attraction between positive and negative ions
define a covalent bond
the strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms
what is a dative covalent bond?
a shared pair of electrons with the electrons being provided by one of the atoms (e.g. NH4+)
what is average bond enthalpy?
the average enthalpy change which
takes place when breaking by homolytic fission one mole of a given
type of bond in the molecules of a gaseous species
a dimer is ..
continuous structure in 3D
define metallic bonding
electrostatic attraction between positive metal ions and delocalised electrons
why are metals insoluble in water?
too much energy is required to break the strong electrostatic forces
can easily be bent in to different shapes
