C2 Chemistry - simple and giant covalent bonding Flashcards
whats an example of simple molecules?
co2
what are simple molecules?
only a few atoms held together by strong covalent bonds
why do simple molecules have low melting and boiling points?
weak intermolecular forces break down easily
why are simple molecules non conductive?
they do not have free electrons or an overall electric charge
what are giant covalent structures?
structures that contain lots of non-metal atoms joined together by covalent bonds
what are the two properties of giant covalent structures
very high melting points
variable conductivity
why do giant covalent structures have very high melting points?
they strong covalent bonds must be broken
why do giant covalent structure have variable conductivity?
the giant structure such as graphie and diamond have different conductivity
