Ammonia (NH3) has a pyramidal shape because of its sp3 hybridization. The lone pair of electrons on the nitrogen atom repels the bonding pairs, causing the molecule to adopt a trigonal pyramidal geometry.
The shape of ammonia is trigonal pyramidal, with the nitrogen atom at the center and three hydrogen atoms forming a pyramid shape around it.
The ammonia molecule (NH3) has a trigonal pyramidal shape, with three hydrogen atoms bonded to a central nitrogen atom.
The molecular shape of ammonia is called trigonal pyramidal. It has three bonding pairs and one lone pair of electrons around the central nitrogen atom, giving it a pyramidal shape.
Ammonia is pyramidal in shape because of the lone pair of electrons on the nitrogen atom. The lone pair repels the bonding pairs, causing the molecule to adopt a trigonal pyramidal geometry for maximum separation between electron pairs.
The shape of an ammonia (NH3) molecule is trigonal pyramidal. It has three hydrogen atoms bonded to a central nitrogen atom with a lone pair of electrons, giving it a distinct pyramidal shape.
