False. In NH3 (ammonia), the nitrogen atom has a partial negative charge, but the statement is false because the nitrogen atom actually has a partial positive charge. Here’s why:
Ammonia (NH3) is a molecule where nitrogen is bonded to three hydrogen atoms. Nitrogen is more electronegative than hydrogen, meaning it has a greater tendency to attract electrons. However, in NH3, the nitrogen atom has a lone pair of electrons, which creates a region of electron density around the nitrogen atom. This lone pair causes the nitrogen atom to have a partial negative charge, while the hydrogen atoms have partial positive charges.
So, the correct statement would be: NH3 has a partial negative charge on the nitrogen atom due to the lone pair of electrons.
