What type of bond will form if an element with a electro negativity of 3.1 bonds to an element of electro negativity of 0.9

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.
