Ionic Radius

  1. Nov 19, 2006 #1
    Hi I have a question involving periodic trends. This time the trend is on ionic radius. I'm not sure I got this right so I was wondering if anyone here may please offer their advice. Thank you!

    Order each of the following ions according to largest to smallest.
    A. [tex]Cl^-[/tex]
    B. [tex]Be^{2+}[/tex]
    C. [tex]Li^+[/tex]
    D. [tex]F^-[/tex]
    E. [tex]H^-[/tex]

    Well have you read about the trend? It will make a lot more sense if you have read the information.

    I have read the trend and I think the answer should be Cl-, H-, F-, Li+, Be2+.

    However, I am not sure about this, because of the hydride. I heard that there is some controversy as what is the actual ionic radius. I just wanted to see if anyone here came up with the same order.

    However, my chem TA disagreed and thinks the hydride should be last. What do you guys think?
