two electrons that from a bond as opposed to two electrons that are lone - giving the phrase lone pair. So on the molecule NH3 there are 3 bond pairs of electrons on the N-H bonds and one lone pair of electrons on the nitrogen.

A pair bond is a strong social relationship between two individuals, often used to describe monogamous mating relationships in animals. Pair bonds can involve exclusive mating, shared parenting responsibilities, and a significant emotional connection.

What is the change in bond angle down a group when central atom has lone pair?
The bond angle decreases down a group when the central atom has a lone pair. This is because the lone pair exerts greater repulsion on the bonding pairs, causing them to move closer together, resulting in a smaller bond angle.
Why ammonia has larger bond angle than nf3?
Ammonia (NH3) has a larger bond angle than NF3 because nitrogen is less electronegative than fluorine. Therefore, the lone pair-bond pair repulsion in ammonia is less significant than the lone pair-bond pair repulsion in NF3, resulting in a larger bond angle in ammonia.
When two chlorine atoms bond they what a pair of electrons?
When two chlorine atoms bond, they share a pair of electrons to form a single covalent bond. Each chlorine atom contributes one electron to form the shared pair, resulting in a stable molecule.
What bond is formed when a pair of electrons is donated to another atom?
A covalent bond is formed when a pair of electrons is shared between two atoms. If one atom donates a pair of electrons to another atom, an ionic bond is formed.
What is the shape of the molecul nitrogen trifluoride?
NF3 has trigonal pyramidal shape. Around nitrogen, there are 1 lone pair electron and 3 bond pair electrons. The lone pair-bond pair electron repulsion is greater than bond pair-bond pair electron repulsion. The angle between N-F bond pairs are 107 degrees

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.
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
Why does a lone pair of electrons occupy more space on an atom?
A lone pair of electrons occupies more space on an atom because it is not being shared with another atom, allowing it to spread out more, leading to increased repulsion between electron pairs and causing the lone pair to push other electron pairs farther apart. This results in the lone pair taking up more space around the atom.
When two chlorine atoms bond they what a pair of electrons?
When two chlorine atoms bond, they share a pair of electrons to form a single covalent bond. Each chlorine atom contributes one electron to form the shared pair, resulting in a stable molecule.
Bond formed by sharing a pair of electrons?
single bond
Bond that evenly shares a pair of electrons?
Covalent bond.
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 is the molecular shape for ph4 plus?
The molecular shape for ( \text{PH}_4^+ ) (phosphonium ion) is tetrahedral. This is because phosphorus has four bonding pairs around it, which results in a geometry with bond angles of approximately 109.5 degrees.
Shared pair of electrons holds a chemical bond called?
A shared pair of electrons that holds a chemical bond is called a covalent bond. In a covalent bond, two atoms share electrons to achieve a stable electron configuration. This type of bond is common in nonmetal compounds and results in a strong connection between the atoms involved.
