Silicate [SiO4] 4- and Phosphate [PO4]3- anions seem to be quite similar when briefly viewed. However, there are subtle differences that differintiate these two molecules. What is the electrostatic valency (or e.v. for short) bond strengths for the phosphate and silicate anions mentioned above? Given the electrosatic valency principal, what is the difference between these molecules relative to the structures for silicate and phosphate minerals? Lastly, I want you to calculate the value of e.v. for both molecules (phosphate and silicate). Remember, this is a three part question. If you do not answer completely you will not be given full credit for this assignment!!

Question

Silicate [SiO₄]^4-and Phosphate [PO₄]^3- anions seem to be quite similar when briefly viewed. However, there are subtle differences that differintiate these two molecules.

What is the electrostatic valency (or e.v. for short) bond strengths for the phosphate and silicate anions mentioned above? Given the electrosatic valency principal, what is the difference between these molecules relative to the structures for silicate and phosphate minerals? Lastly, I want you to calculate the value of e.v. for both molecules (phosphate and silicate).
