Three Hydrogen atoms are bonded to a central atom. The central atom has a full octet. What is its electron geometry (basic domain), and its molecular geometry (molecular domain)? Also indicate whether it is polar or nonpolar, and why. (Hint it may help to draw a Lewis structure)

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the answer is 75.0%.
