Is NH3 a trigonal pyramidal?
It is pyramidal in shape.It has a lone pair.
Does a lone pair consist of a nonbinding pair of electrons?
Yes. Ammonia or triethylamine would be classic molecules to illustrate. With ammonia - NH3, the nitrogen has 5 valence electrons in total. Three of those electrons share with 3 electrons from 3 hydrogens to form 3 covalent N-H bonds. The other two valence electrons are a lone pair. They do not take part in bonding.
What is the shape of AlF3NH3?
Octahedral. The bond between N and Al doesn't count as a bond pair as it is a dative bond, since both electrons were donated by the lone pair on the N in NH3
What effect does a lone electron pair have on molecular shape?
The lone pair pushes bonding electron pairs away.
What is the definition of lone pairs of electrons?
The lone pair electron region is the place around the central atom where electrons not bonding with another atom can be found. A lone pair of electrons are electrons that are not bonded with other atoms.
