Knowing the electron configuration helps us understand the elements’ behavior at the atomic level and therefore helps us understand the properties of elements as we see them on the macroscopic level. How is it the same as understanding other people’s behavior as well?

h let me think

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: )
