Molecular Structure: Thorium & Rubidium; Thorium & Phosphour

Click For Summary
SUMMARY

The discussion focuses on predicting the molecular structures formed by combining thorium with rubidium and phosphorous. The electronegativity values indicate that the bond between thorium and rubidium is polar covalent (ΔEN = 0.48), while the bond between thorium and phosphorous is also polar covalent (ΔEN = 0.89). The participant seeks guidance on drawing Lewis diagrams and VSEPR models, as well as predicting geometry, bond angles, bond energy, bond length, and polarity for these compounds. The nature of thorium as an actinide and rubidium as an alkali metal suggests a metal-substance interaction, while the interaction with phosphorous involves a nonmetal.

PREREQUISITES
  • Understanding of Lewis structures
  • Familiarity with VSEPR theory
  • Knowledge of electronegativity and its implications for bond polarity
  • Basic concepts of molecular geometry
NEXT STEPS
  • Research how to draw Lewis diagrams for metal-nonmetal compounds
  • Study VSEPR theory to predict molecular geometry and bond angles
  • Learn about bond energy and bond length in polar covalent bonds
  • Investigate the properties of actinides and their interactions with nonmetals
USEFUL FOR

Chemistry students, educators, and anyone interested in molecular structure and bonding, particularly in the context of actinides and their interactions with other elements.

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?
