According to the octet rule most elements need _______ valence electrons.

• 2

• 8

• 6

• 18

Which of these could be the lewis dot diagram for an oxygen anion?

• A

• B

• C

• D

Answer explanation

Oxygen has 6 valence electrons, but it wants 8. Therefore, it will steal 2 electrons so that it has a total of 8 electrons. Choice A has 8 electrons.

What is a valence electron?

• electron found in a middle shell

• electron found in outermost shell

• electron found in innermost shell

• electron not found in a shell
