1. Artificial diamonds are made using thallium carbonate. If thallium has an oxidation number of 1+, what is the formula for the compound? 2. Explain what electric forces between oppositely charged electrons and protons have to do with chemical reactions.

3. If the linear molecule beryllium dichloride (BeCl₂) has polar bonds because CI attracts electrons more strongly than Be, why is the molecule nonpolar?

 Artificial diamonds are made using thallium carbonate. If thallium has an oxidation number of 1+ number 2  A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. number 3 giant metallic, giant ionic, simple molecular, and macromolecular ... it has positive ions surrounded by a sea of delocalised electrons ... m/z value than Cl⁻. this means that F⁻ is more attracted to the Ca²⁺ ion more strongly ... What bond angle does beryllium chloride, BeCl₂ have? ... Give two examples of linear molecules.
