1s^2 2s^2 2p^6 3s^2 3p^6 how many unpaired electrons are in the atom represented by the electron configuration above?

0 unpaired

Explanation:

the electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^6, can also be written in noble gas configuration as [Ne] 3s^2 3p^6 which translates to the element Argon ( Ar ). Since the outer shell is full with 8 valence electrons, there is no lone electron so all elections are paired.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
