Ammonium phosphate nh43po4 is an important ingredient in many fertilizers. it can be made by reacting phosphoric acid h3po4 with ammonia nh3 . what mass of ammonium phosphate is produced by the reaction of 2.6g of phosphoric acid? round your answer to 2 significant digits.

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.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
