Any help is greatly appreciated :)!! An object was measured by a worker as
15.9cm long, however, the manufacturer
specifications list the length of the object at
15.8cm. What is the percent error in the
workers measurement? A 0.629 B 0.633

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: )
