    Hey guys,

    Love the book. Thank you so much.

    Not sure if it is misleading to say

    "Group VIIIA elements: He, Ne, Ar, Kr, Xe all have 8 electrons in the valence shell."

    "He" has two electrons and it is a noble gas because its outter most shell is filled. I'm not 100% sure on this. But thought of bringing it up.

    This is found in the "Valence and Crystal Structure" of Volume III


    Thanks again guys,

    -Andy

    Absolutely, it is incorrect to include He in that grouping.

    It should leave He out of that sentence and add another sentence saying He has a K shell as it's outermost shell and, as such, is filled with only two electrons.

    On that note, toward the top of the page, we see:
    The L shell is filled with 8 electrons. It means to say the K shell, I believe.

    Hello,

    Here is a picture with how the shells are filled on the noble gasses:
