In chemistry, a lone pair is a pair of valence electrons that are not involved in bonding and are therefore considered non-bonding. Lone pairs are found in molecules with a structure that includes regions of non-bonding electrons. They can affect the shape and chemical properties of molecules.

How many charge clouds does NF3 have?
NF3 has four charge clouds, consisting of three bonding pairs and one lone pair around the central nitrogen atom. This results in a trigonal pyramidal molecular geometry for NF3.
Is ICl4- a square planar and polar?
Yes, it is square planar. The central iodine atom exceeds the octet rule by bonding with all four chlorine atoms and having two lone pairs. A central atom with six electron pairs (d2sp3 hybridization) and two lone electron pairs by definition is square planar (see VSEPR theory for more information). Because of its symmetrical geometry, it will have no dipole moment.
What is the electron pair geometry for so3?
The molecular geometry of the AsO2- ion is bent (because of the lone electron pair with the central arsenic atom, making the O-As-O bond angle very obtuse) but its electron domain geometry is trigonal planar because there are three domains, with a 120 deg. angle between them.
What are electron groups?
Electron groups are pairs of electrons that exist around an atom, either in a single bond, double bond, triple bond, or lone pair. These electron groups determine the geometry of the molecule and play a significant role in determining its reactivity and properties.
What is responsible for the bent nature of NH3?
There are 3 bonding pairs of electrons N - H and one lone pair . The repulsion forces between lone pair -lone pair is > lone pair -bond pair > bond pair - bond pair. So the lone pair causes distortion from a perfect tetrahedron
How many lone pair of electrons are there in ammonia?
one lone pair of electrons
What is the change in bond angle down a group when central atom has lone pair?
there is repulsion between lone pair and bond pair for example in water molecule oxygen has lone pair which repells the bond pair due to this bond angle decreases simply ddue to repulsion btween lone pair to lone pair or lone pair to bond pair angle varies
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.
Why the repulsion caused by lone pair is greater than bonding pair?
lone pair has more electrons than bond pair
How does a lone pair distort a molecular pair?
A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs. So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.
Why the lone pair lone pair repulsion is maximum?
Lone pair-lone pair repulsion is maximum because both lone pairs are localized around the same atom, leading to a strong electrostatic repulsion due to their negative charge densities being in close proximity. This results in a greater repulsion compared to other interactions like lone pair-bonding pair or bonding pair-bonding pair repulsions.
What takes up more space a lone pair or a single bond?
A lone pair
How does a lone pair distort molecular shape?
A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs. So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.
How does a lone pair distort the molecular shape?

So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.
Diffirences of bonded and lone pair electron?
The difference between bonded and lone pair is that a bond pair is composed of two electron that are in a bond whereas lone pair is composed of two electron that is not a bond.
How many lone pair electrons are in ch2o?
There is 1 lone pair around the central C atom
