The nitrate ion (NO3-) does not have a lone pair on the nitrogen atom. In its resonance structures, nitrogen forms three bonds with oxygen atoms, and the overall charge of -1 is delocalized across the oxygen atoms. However, each oxygen atom in the nitrate ion does have two lone pairs. Thus, while nitrogen does not have a lone pair, the oxygen atoms do.
lone pair has more electrons than bond pair
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.
A lone pair
nitrogen aton in NH3 has one lone pair of electron
There are no lone pairs in the nitrate ion (NO3-). The nitrogen atom forms three sigma bonds with oxygen atoms, leaving no non-bonding pairs of electrons.
CN- is a stronger base than NO3-. This is because CN- can act as a Lewis base by donating a lone pair of electrons to a proton, while NO3- cannot readily donate electrons in the same way.
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
one lone pair of electrons
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
they are the same. Lone pair is unshared pair of electrons and bond pair is shared pair of electron.
lone pair has more electrons than bond 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.
