bonding Flashcards
(15 cards)
what is ionic bonding between
metal and non metals
what is an example of an ionic bond
potassium chloride
definition of ionic bonding
transfer of electrons
what type of attraction is ionic
electrostatic force of attraction acting between oppositely charged ions
what is the structure of ionic
giant ionic
properties of ionic
high BP MP lot of heat energy required to break
not electrical conductors- but can when melted
what are the 2 different types of covalent
giant and simple
what is covalent bonding between
non metals
example of covalent bond
oxygen
definition of covalent bond
shared pair of electrons
what type of attraction for covalent bond
electric force of attraction acting between pairs of electrons and the nuclei of both atoms
properties of simple covalent
low MP BP
weak inter molecular forces of attraction require little heat energy to break
what are two types of diagram for giant covalent
diamond
graphite
properties of giant covalent diamond
high MP BP require a lot of heat energy to break
lots of strong covalent bonds
properties of giant covalent graphite
lubricated layers slide over each other
conducts electricty
layers held by weak inter molecular forces so slide over each other
