Which of these is a typical property of a substance that is composed of atoms that are held together by covalent bonds?
a. it conducts electricity when in solid form.
b. it conducts electricity when in molten form.
c. it conducts electricity when it is dissolved in water.
d. it does not conduct electricity in any form.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
