Question

What is The shape of a NH3 molecule?

Answer 1

аммиак-NH3, надеюсь я правильно поняла вопрос

Answer 2

The shape of an NH3 (ammonia) molecule is trigonal pyramidal.

NH3 consists of one nitrogen (N) atom bonded to three hydrogen (H) atoms. The nitrogen atom is at the center, and the three hydrogen atoms are arranged around it. The bond angles in ammonia are approximately 107 degrees, which gives it a pyramidal shape. This shape is a result of the lone pair of electrons on the nitrogen atom, which exerts greater repulsion on the bonding electron pairs, causing the hydrogen atoms to be pushed slightly downward from a perfect tetrahedral arrangement.

In summary, the NH3 molecule has a trigonal pyramidal shape due to its three hydrogen atoms arranged in a pyramid-like fashion around the central nitrogen atom.
