Homework Help: Molecular structure

  1. Nov 2, 2014 #1
    1. The problem statement, all variables and given/known data

    Got a homework question for what kind of molecular structure you would get by combining
    these to metals: Thorium and rubidium, thorium and phosphour. Got to draw the Lewis diagrams and VSEPR model for these molecular structures, and predict the geometry - bond angles - bond energy - bond length - polarity

    2. Relevant equations

    Electronegativity Th: 1.3 (valence 4)
    Electronegativity Rb: 0.82 (valence 1)

    Delta EN: 1.3 - 0.82 = 0.48 -> abit polar covalent

    Electronegativity Phosphour: 2.19 (valence 5)

    Delta EN: 2.19 - 1.3 = 0.89 -> polar covalent

    3. The attempt at a solution

    Since thorium is an actinide metal and rubidium an alkaline metal, I guess this would turn out to be a metal-substance. The thorium and phosphour I'm not sure about, but since phosphour is a nonmetal it lacks mostly metallic attributes. What would be the geometric figurines for these molecular structures?

    Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
