Name the difference(s) between an plant and animal cell? question 1 options: a animal cells do not contain chloroplasts b animal cells are not surrounded by cell walls c the vacuoles in plants are much larger than those of animals d all of the above

answer should be d :)

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: )
