In terms of struture, lone pairs contribute helping a molecule acquire a shape as dictated by VSEPR Theory (Valence Shell Electron Pair Repulsion Theory).
Regarding chemical properties lone pair/s of electrons can make a molecule act as a Lewis base (like ammonia) in the reaction mixtures the extent of which depends on various other features in the structure of molecule.
What else can I help you with?
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.
How many lone pairs of electrons in if5?
If an atom has five valence electrons, it will have one lone pair of electrons.
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 difference between lone pair and bonding pair electron?
they are the same. Lone pair is unshared pair of electrons and bond pair is shared pair of electron.
