Homework Help: How to predict which elements will have a certain oxidation state?

  1. Oct 5, 2011 #1
    1. The problem statement, all variables and given/known data

    I have a test coming up and some of the practice questions were things like "Name 6 elements with a maximum oxidation state of +7" or some other number like +8, +6, etc. How do I go about doing this?

    3. The attempt at a solution

    There is the obvious trick of counting valence electrons, but past that how do I figure stuff like this out? How do i know which noble gases have what oxidation states?

    I already have to memorize the periodic table for this test, I'd hate to have to memorize all the random oxidation states of elements too.

    If you know PT, valence electrons depend on the position of the element.
