If an atom has 3 electrons in its second shell and its first shell is filled it will tend to?
A. lose 3 electrons from its second shell
B. lose all of the electrons from its first shell
C. lose all of the elctrons from its first and second shells
D. gain electrons in its second shell
Personally, I think the answer is A. however, my book doesn't give an example that fits this question. The main reason I think this is the book doesn't discuss losing electrons in the first shell so that eliminates the possibility of B. or C. leaving the answer D. which is eliminated because where will it gain the extra electrons from. Further more the shells only gain electrons when they are trying to stabalize by having 8. I don't know, I could be wrong, but my logic makes sense to me.

If I understand the question correctly, you re right in saying A, during reactions, the inner shells are not touched and the only one in use is the outer one and there are still few enough electrons to be more efficient in losing than gaining to make shells full.
