1

whats an example of simple molecules?

co2

2

what are simple molecules?

only a few atoms held together by strong covalent bonds

3

why do simple molecules have low melting and boiling points?

weak intermolecular forces break down easily

4

why are simple molecules non conductive?

they do not have free electrons or an overall electric charge

5

what are giant covalent structures?

structures that contain lots of non-metal atoms joined together by covalent bonds

6

what are the two properties of giant covalent structures

very high melting points
variable conductivity

7

why do giant covalent structures have very high melting points?

they strong covalent bonds must be broken

8

why do giant covalent structure have variable conductivity?

the giant structure such as graphie and diamond have different conductivity
