why is nh3 tetrahedral
Thus, the compound of ammonia is in a trigonal pyramidal shape or in a tetrahedral sphere because as atoms form bonds at 107.8 degrees, 4 pairs of electrons formed by the 5 valence electrons of nitrogen and the 3 electrons of hydrogen are distributed equally around the molecule.his chemical compound is basically formed from the basic elements of nitrogen and hydrogen, in the absence of water. As early as the 8th century, salts of ammonia have already use by Muslim alchemists and, during the 13th century, this substance was use by European alchemists to alter colors of vegetable dyes.
