Molecular Structure: Thorium & Rubidium; Thorium & Phosphour

[TeslaPow]

Homework Statement

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

Homework 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

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?
