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 A pair of electrons not involved in bonding called?
Such pairs of electrons are called as lone pairs.
What effect does lone pair electrons have on molecular shape?
The lone pair pushes bonding electron pairs away.
How many lone pair electrons are in ch2o?
There is 1 lone pair around the central C atom
How many lone pairs are there on nitrogen?
Two lone pair

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
What is A pair of electrons not involved in bonding called?
Such pairs of electrons are called as lone pairs.
Why the lone pair lone pair repulsion is maximum?

How many lone pair of electrons are there in ammonia?
one lone pair of electrons
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.
What takes up more space a lone pair or a single bond?
A lone pair
