Andrea said that if then must also be equal to 40°. Which justifies Andrea’s statement?

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.

i think its 100

i hope this !

c. electrical charges of ionic bonds.
