Pseudophryne. The corroboree frog is incredibly distinctive with its bright yellow and black striped skin. The upper surface has a rough texture whilst the belly is smooth and either black and yellow or black and white.Females are larger in size than males and, unusually, neither sex has webbed toes.seudophryne.

(b) P4 is non polar covalent. (c) BF3 is non polar covalent molecule (individual B-F bonds are polar but the net dipole moment is zero due to its triangular planar geometry).b) P4 is non polar covalent.

A step-by-step explanation of how to draw the PO4 3- Lewis Structure (Phosphate Ion). For the PO4 3- Lewis structure use the periodic table to find the total number of valence electrons for the PO4 3- molecule.Once we know how many valence electrons there are in PO4 3- we can distribute them around the central atom with the goal of filling the outer shells of each atom.In the Lewis structure of PO43- there are a total of 32 valence electrons.For the Lewis structure for PO4 3- you should take formal charges into account to find the best Lewis structure for the molecule.Remember, PO4 3- has a negative three charge on the molecule.nce we know how many valence electrons there are in PO4 3- we can distribute them around the central atom with the goal of filling the outer shells of each atom. In the Lewis structure of PO43- there are a total of 32 valence electrons.
