    It is necessary a review on the answer of how many electrons are in the outer shell os Arsenic. The correct aswer is 5.

    why does the answer show the number of electrons in the outer shell as 8? it is 5, right?

    there are only 5e on outer shell for AS not 8

    The animated answer for Arsenic has an incorrect answer: How many electrons in the outer shell? There are 5 electrons is the correct answer. The animations says there are 8 (which is incorrect).

    there are clearly 5 electrons on the outer shell for Arsenic, but the answer says that there are 8

    Arsenic has 5 electrons in the outermost shell. First shell = 2e, Second shell = 8e, Third shell = 18e, and Forth shell = 5e _(Electronic Configuration per shell: 2, 8, 18, 5).

    The exercise on Sulfur asks "How many shells does it have?" twice, but will only give you the option to answer once you have filled the second one with the atomic structure in chemical shorthand.

    how the shell well hold 18 electrons is'nt the maximum number is 8

    I think the 5th question is a repeat of the 4th
