carbon and silicon dioxide

Question 6

do covalent substances ever conduct

Answer 6

no

Question 7

do ionic substances ever conduct

Answer 7

when liquid or in a solution

Question 8

do metallic substances ever conduct

Answer 8

in solid and liquid form yes, and they don’t dissolve

Question 9

ionic bond defintion

Answer 9

the electrostatic attraction between oppositely charged ions

Question 10

ionic lattices

Answer 10

have very strong ionic bonds, that take a lot of heat energy to break down

Question 11

why do ionic compounds conduct in a liquid or solution

Answer 11

because the ions are free to move

Question 12

do not conduct

high melting point solids

Answer 12

covalent network

Question 13

do not conduct
low melting point/usually liquids or gases
strong covalent bonds between atoms but weak forces between molecules

Answer 13

discrete molecular

Question 14

why do atoms bond

Answer 14

to complete outer shells

to become more stable

Question 15

in ionic bonds the atoms………..electrons

Answer 15

transfer

Question 16

in covalent bonds the atoms………..electrons

Answer 16

share electrons

Question 17

metal atoms become

Answer 17

positive ions

Question 18

non metal atoms become

Answer 18

negative ions

Question 19

what holds covalent bonds together

Answer 19

the positive charge of both atoms attract the negative charge of the shared pair of electrons.
(opposites attract)
