ionic bonding Flashcards
(9 cards)
what is the definition of ionic bonding?
the electrostatic attraction between oppositely charged ions
under what conditions can an atom undergo ionic bonding?
an atom with low IE (cation) must bond with an atom of high electronegativity
list the elements with the highest electronegativity
F, O, N, Cl, Br
define electronegativity
the power of an atom to attract electrons to itself
what must the difference in electronegativity be between two elements to be considered ionic bonding?
diff in EN must be more / equal to 2. (otherwise covalent bonding)
is an ionic bond weak or strong?
strong
what phase is an ionic bonding?
solid
does ionic bonding have a high or low melting point?
high
show ionic bonding
