Molecular Structure: Thorium & Rubidium; Thorium & Phosphour

In summary, the homework question asks for the molecular structures formed by combining Thorium and Rubidium, as well as Thorium and Phosphour. The Lewis diagrams and VSEPR model need to be drawn, and the geometry, bond angles, bond energy, bond length, and polarity must be predicted. With the given electronegativities, the combinations of Th and Rb and Th and P would result in polar covalent bonds. The geometric figures for these structures are not specified.

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?

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?
 

1. What is the molecular structure of Thorium and Rubidium?

The molecular structure of Thorium and Rubidium is ionic, with Thorium having a positive charge and Rubidium having a negative charge. They form a crystal lattice structure, with the Thorium atoms surrounded by Rubidium atoms.

2. What are the properties of Thorium and Rubidium?

Thorium is a radioactive element with a silvery color and high density. It has a low melting point and reacts with water and air. Rubidium is a soft, silvery-white metal with a low melting point and reacts strongly with water and air.

3. How does the molecular structure of Thorium and Phosphorus differ from Thorium and Rubidium?

The molecular structure of Thorium and Phosphorus is covalent, meaning the atoms share electrons to form bonds. This results in a molecule with a more complex structure compared to the ionic lattice of Thorium and Rubidium.

4. What are the uses of Thorium and Rubidium?

Thorium is used in nuclear reactors as a fuel source and in certain types of glass and ceramics. Rubidium is commonly used in atomic clocks, as well as in the production of photocells and special glass.

5. Are there any health or safety concerns associated with Thorium and Rubidium?

Thorium is a radioactive element and can be harmful if ingested or inhaled. However, the risk is low as it is not often found in high concentrations. Rubidium is not considered toxic, but it can react violently with water and should be handled with caution.
