Hi. Is PO4(3-) polar or non-polar? Why or why not? Thanks! Look up the electronegativity of P and O. I think I remember that O is about 3.5 and P is about 2.1; therefore, each P-O bond is somewhat polar. Thus, the ion will be polar unless the Lewis structure (electron dot ...

the primary structure consisted of beta-pleated sheet..so the secondary structure is where the structure coiled and characterized by an alpha-helix. i don't about random coils... i chose hydrogen bond but its wrong..so its alpha helix....
