Why can't NH_3_ donate a proton and act as a Bronsted-Lowry acid?

    NH3 has that single pair of unshared electrons (the lone pair on the left) which is just right for a bare proton (H^+) to move to. To DONATE a proton means it must break a N-H bond (in order to free up a bare proton) which takes energy.

    That cleared it up a bunch. Thank you so much!
