C2 Bonding Flashcards
what is an IONIC bond?
between metal and non-metal
electrons transferred → atoms fill outer shells and
form ions
what is a COVALENT bond?
between non-metals
pairs of electrons shared → atoms fill outer shells
do SOLID-state IONIC BONDS conduct electricity? why?
no
ions are bonded and not free to move
do LIQUID-state IONIC BONDS conduct electricity? why?
yes
ions are free to move
do IONIC BONDS have high or low m/b points? why?
high
strong electrostatic force of attraction between oppositely charged ions → more energy needed to break the bonds
do SIMPLE MOLECULAR BONDS conduct electricity? why?
no
electrons are not free to move
do SIMPLE MOLECULAR BONDS have high or low m/b points? why?
low
weak intermolecular force of attraction → less energy needed to break the bonds
does DIAMOND conduct electricity? why?
no
no delocalized electrons
does GRAPHITE conduct electricity? why?
yes
delocalized electrons
do GIANT COVALENT BONDS have high or low m/b points? why?
strong covalent bonds → more energy needed to break the bonds
